The 2010s were a year of love -- and a year of heartbreak.
While Hollywood isn't known for its lasting marriages, it has produced a few couples we truly believed were meant to be together. From Jennifer Garner and Ben Affleck to Brad Pitt and Angelina Jolie, we had faith that love could survive amid the pressures of the limelight. Then, that love crashed and burned.
For some, infidelity tore them apart. For others, it was the stress of success or just growing distant from each other. We fell in love with their nicknames, their PDA pics and their power couple auras, but as they say, all good things must come to an end. Here are the 13 most shocking splits of the decade:
Justin Bieber and Selena Gomez
Bieber and Gomez's off-and-on romance literally spanned the entire decade, with the "Sorry" singer making his first public move by serenading the actress during his performance of "One Less Lonely Girl" during Dick Clark's New Year's Rockin' Eve special on Dec. 31, 2009. They made their red carpet debut as a couple in 2011 and broke up for the first time in 2012. They were back together by 2013, but split again in 2015. They reconnected in 2017, following Gomez's kidney transplant, but by March 2018, their relationship ended again -- this time for good. Months later, Bieber was spotted with his now-wife Hailey Baldwin. He proposed to her in July 2018, and they tied the knot at a New York City courthouse in September of that same year. The model officially changed her last name to Bieber shortly after they said "I do."
While the Jelena romance didn't last, we'll always have the songs to remember it by. They gifted us with "The Heart Wants What It Wants," "Where Are U Now," and Gomez's new song, "Lose You to Love Me."
Brad Pitt and Angelina Jolie
Jolie filed for divorce from Pitt in 2016 after just two years of marriage, but after over a decade together -- and with six children -- their split was far from undramatic. The pair fell in love while filming Mr. & Mrs. Smith in 2004, while Pitt was still married to Jennifer Aniston. By 2006, Pitt's divorce from Aniston was finalized, and Jolie was pregnant with his child. As their family grew, so did their star power, solidifying themselves as the world's most famous celebrity couple. Brangelina tied the knot in 2014, and starred in one last film together, By the Sea, in 2015, which Jolie also directed. Then, on Sept. 20, 2016, Jolie shocked the globe by filing for divorce.
A source told ET at the time that the sad split had been "a long time coming." Contentious battles over custody of the pair's six children followed, but a separate source told ET earlier this year that Pitt and Jolie's relationship is at the best place it's been since their split.
Channing Tatum and Jenna Dewan
Tatum and Dewan's 2018 separation ripped our Step Up-loving hearts apart. The couple, who fell for each other while starring as love interests in the 2006 dance movie, announced in April 2018 that they were calling it quits after eight years of marriage. A source told ET at the time, "They have been fighting the last couple of years -- quite a bit. "There is a sense of relief on both of their parts. They have tried working on things and had therapy but nothing changed."
The former couple shares one child, 6-year-old daughter Everly, and have made her a priority amid their split. By October 2018, Tatum had moved on with Jessie J, while Dewan starting dating actor Steve Kazee; Dewan and Kazee are now expecting their first child together. Tatum and Dewan finalized their divorce last month.
Jennifer Garner and Ben Affleck
2015 was the year of several high-profile splits, from Emma Stone and Andrew Garfield to Gwen Stefani and Gavin Rossdale, Blake Shelton and Miranda Lambert, Kourtney Kardashian and Scott Disick and more -- but Garner and Affleck's breakup truly shocked us all. The pair, who share three children together, announced their separation in June 2015, after 10 years of marriage. They filed for divorce nearly two years later, in April 2017, and finalized their divorce in August 2018.
Despite their split, the former couple has remained on good terms, with Garner supporting her ex's struggles with sobriety and even driving him to rehab last year. A source told ET at the time that the actress has "been Ben's rock."
Katie Holmes and Tom Cruise
Holmes and Cruise's 2012 split was just as mysterious as their marriage. The two got engaged in June 2005, just seven weeks after meeting, and welcomed their daughter, Suri, in April 2006, on the one-year anniversary of their first date. They married just a few months later in November 2006, in a Scientology ceremony in Italy.
All seemed well until Holmes filed for divorce from Cruise in June 2012, after five and a half years of marriage. Ten days later, the actors' attorneys announced that they had signed a divorce settlement; Holmes has custody of Suri and neither has offered public insight into their marriage or divorce since.
Chris Pratt and Anna Faris
Pratt and Faris were the couple everyone wanted to hang out with before their shocking split in August 2017, after eight years of marriage. Their separation announcement came months after they appeared happy and in love at the Guardians of the Galaxy Vol. 2 premiere that April; they gushed to ET over each other on the red carpet.
They filed for divorce at the same time last December and finalized their divorce in November 2018. The two have since remained on good terms. Pratt and Faris have even been spotted hanging out with both of their new significant others and their 7-year-old son, Jack. Faris is dating cinematographer Michael Barrett, and Pratt married Katherine Schwarzenegger earlier this year.
Kristen Stewart and Robert Pattinson
Stewart and Pattinson's real-life romance had Twihards in a tizzy -- but it all came to a crashing halt in July 2012. The pair, of course, met and fell in love while playing Edward and Bella in 2008's Twilight, and while they kept details of their romance private, fans couldn't get enough of how the onscreen love story transitioned offscreen. Then, Stewart's affair with her Snow White and the Huntsman director, Rupert Sanders, went public.
Pattinson and Stewart broke things off after the news, but ended up reconciling months later, in October 2012, just in time to promote The Twilight Saga: Breaking Dawn Part 2, which premiered that November. Their relationship couldn't survive, and they broke up for good in May 2013.
Sandra Bullock and Jesse James
Infidelity also rocked Bullock's marriage to James. The movie star's unlikely relationship with the motorcycle builder and Monster Garage host began in the early 2000s, after she arranged for her godson to meet James as a Christmas present. Bullock and James married in 2005, and they stood by each other's side throughout his custody battle with his second wife, Janine Lindemulder. Then, in March 2010, several women came forward claiming to have had affairs with James. Bullock canceled promotional appearances for The Blind Side, citing "unforseen personal reasons." The news came months after Bullock had started the adoption process with a baby boy from New Orleans.
Amid the headlines, James released a statement asking for Bullock's forgiveness. He checked into a rehabilitation facility to try to save the pair's relationship, but Bullock filed for divorce in April 2010. Their divorce was finalized months later, that June, and Bullock adopted the baby boy, Louis, as a single parent.
Ariana Grande and Mac Miller
Grande and Miller's romance may not have lasted as long as some of the other couples on this list, but their split was devastating nonetheless. One month after romance rumors sparked in August 2016, the pair went Instagram official; they were inseparable after that. Miller was by Grande's side after the 2017 Manchester Arena bombing, in which 22 people were killed in a terrorist attack following her Manchester concert. He joined her for a sweet duet during her One Love Manchester concert to aid those affected by the attack.
Engagement rumors swirled as Grande sported a large ring on that finger during the performance, but several months later, she and the rapper called it quits. The pair's relationship was complicated, and when Miller was arrested on a charge of DUI just weeks after their breakup, Grande found herself fighting back against fans who said she was responsible. "I have cared for him and tried to support his sobriety and prayed for his balance for years (and always will of course) but shaming/blaming women for a man’s inability to keep his sh*t together is a very major problem," she said. By June 2018, Grande was engaged to Pete Davidson.
Miller tragically died in September 2018, at just 26 years old. One month later, Grande ended her engagement to Davidson.
Liza Koshy and David Dobrik
The YouTube supercouple built over 20 million followers during the course of their relationship from 2015 to late 2017, but they didn't announce their split until June 2018. In an emotional video, Koshy and Dobrik revealed they had broken up six months prior, admitting that the pressure of their YouTube careers had been a factor in them calling it quits.
Dobrik revealed it was Koshy who had initiated the split because he had been "distant" and busy. They explained they kept it a secret for months because they were "angry" that they allowed themselves to become so distant in the first place -- and left the door open for a possible reconciliation in the future.
Jennifer Lopez and Marc Anthony
Lopez and Anthony's romance was a definite whirlwind. The pair got married in June 2004, just six months after her split from then-fiance Ben Affleck. Lopez and Anthony's star power was undeniable. She referenced her relationship with Anthony in several tracks on her 2005 album, Rebirth, and in 2007, she and Anthony embarked on a co-headlining tour together. A year later, the couple welcomed twins Emme and Max, with the first photos of the babies becoming the most expensive celebrity picture at the time, with People paying a reported $6 million.
Three years later, Lopez and Anthony announced their split. Anthony filed for divorce in April 2012, and their divorce was finalized in 2014, with Lopez retaining primary physical custody of the twins. The former couple remains friendly to this day and even shocked fans by sharing a sweet kiss during his performance at the Latin GRAMMYs in 2016. Lopez is now engaged to Alex Rodriguez.
Mariah Carey and Nick Cannon
Another pair of friendly exes is Carey and Cannon, who separated in August 2014, after six years of marriage. The two first met while shooting the music video for her song, "Bye Bye," on an island off the coast of Antigua, and the world couldn't believe it when the unlikely couple tied the knot in April 2008. Three years later -- to the day -- Carey gave birth to the couple's twins: daughter Monroe and son Moroccan.
Cannon and Carey's split was one of the most amicable in Hollywood, with Cannon fiercely defending his ex in a lengthy Twitter rant shortly after they went their separate ways. The actor filed for divorce in 2014, and their divorce was finalized in 2016. They continue to co-parent their now-8-year-old children.
Kim Kardashian and Kris Humphries
The second time was not the charm for Kim Kardashian, whose marriage to Kris Humphries lasted just 72 days before she filed for divorce in 2011. The pair's star-studded Montecito, California, wedding in August 2011 aired in a two-part special on E! in October 2011. The reality star also released a wedding fragrance, "Kim Kardashian Love," to mark the nuptials. On Oct. 31, Kardashian filed for divorce.
The media blitz surrounding the wedding -- and subsequent divorce filing -- was unlike anything seen at the time, with many accusing Kardashian of marrying Humphries for publicity. By April 2012, the Keeping Up With the Kardashians star was dating Kanye West; she and Humphries didn't finalize their divorce until June 2013, just days before she welcomed her first child with West, daughter North. Kardashian tied the knot with West in Italy in May 2014.
