All good things must come to an end, but that doesn't make it any easier to handle. Some of Hollywood's cutest couples called it quits this year, and ET is counting down the biggest splits.

Bruce and Kris Jenner: A judge signed legal documents on Dec. 16, finalizing Kris and Bruce's divorce. However, the two won't be officially divorced until March 23, 2015, due to the six-month legal requirement. In October, Kris commented to ET about Bruce's headline-making appearance, specifically the long locks he was photographed with at an Elton John concert that month. "I don't know what he's going through right now," she said about his changing appearance. "I think he's just very happy and I think every time he makes a change in his life -- whether it's emotional or physical or whatever he's doing -- somebody's going to comment on whatever look you have going on for the day." Kris is rumored to be dating Corey Gamble, who works for Justin Bieber's manager Scooter Braun's SB Projects.
Jennifer Lopez and Casper Smart: The former lovebirds called it quits after more than two years of dating. J. Lo was first romantically linked to the 27-year-old backup dancer in November 2011, just four months after her split from her third ex-husband Marc Anthony. In January 2013, J. Lo spoke about her relationship with Casper to Harper's Bazaar, saying, "I can tell him everything, when I'm feeling down, when I'm feeling good. He gives moral support, endless love and support."
Mariah Carey and Nick Cannon: Nick and Mariah split after six years of a seemingly fairy tale marriage. Trouble was first suspected when Mariah spilled on Valentine's Day that she would be "sitting at home alone." Months later, Nick revealed to ET in October that he had plans to cover up his back tattoo bearing Mariah's name.
Melanie Griffith and Antonio Banderas: The estranged couple gave a joint statement to ET in June announcing their separation: "We have thoughtfully and consensually decided to finalize our almost twenty-year marriage in a loving and friendly manner honoring and respecting each other, our family and friends and the beautiful time we have spent together." After the announcement, Melanie was spotted with her "Antonio" tattoo removed.

Tim Burton and Helena Bonham Carter: The former Hollywood power couple, who never officially married, announced their split Dec. 23 after 13 years together. They separated earlier this year but have "continued to be friends and co-parent their children," according to Helena's rep. Tim and Helena have two children together, 11-year-old son Billy and 7-year-old daughter Nell. Suspicion about their relationship arose when Helena was absent from Tim's Big Eyes cast list, as she has frequently appeared in his films.
Robin Thicke and Paula Patton: Robin and Paula split amid infidelity rumors. Robin made a public plea to win Paula back, and even named an album after her, but none of it stopped the actress from filing for divorce in October. The estranged couple had been together for 21 years and married for nine. They first announced their separation in a joint statement, saying, "We will always love each other and be best friends. However, we have mutually decided to separate at this time." The Baggage Claim star cited irreconcilable differences in her filing, and asked for joint legal and physical custody of their son, 4-year-old Julian Fuego Thicke.
