Dancing With the Stars kicks off its 24th season on Monday, March 20.
Ahead of the premiere, airing at 8 p.m. ET on ABC, ET's breaking down the dance competition's most memorable moments of all time.
From major missteps to behind-the-scenes drama, here's 11 of our favorite bombshells from DWTS history.
1. Lochtegate continues.
Fresh off his gold medal-winning victory for Team USA during the 2016 Summer Olympics in Rio and in the middle of a major controversy due to his false report of being robbed at gunpoint following the games, the swimmer traded in his Speedo for sparkly ballroom costumes in hopes of restoring his image during the show's most recent 23rd season.
But during week one, two protesters stormed the stage while he and Cheryl Burke were performing, proving Lochtegate was far from over. Sam Sotoodeh and Barzeen Soroudi were wearing "anti-Lochte" T-shirts and did not have tickets to the ABC taping when they were booked for trespassing. Regardless, Lochte and Burke did OK in the competition, finishing in seventh place.
2. Kelly Monaco's wardrobe malfunction.
Despite almost losing her top while dancing samba with Alec Mazo during week four of DWTS' first season, the General Hospital star and her partner walked away with the first-ever mirror ball trophy.
3. Marie Osmond faints awaiting the judges' critiques.
Paired with Jonathan Roberts, the singer placed third on the fifth season of DWTS. Although her and Roberts' dances were entertaining and fun week after week, it's hard not to forget about her major onstage oops. During the fifth week of the competition, she fainted on live TV as the judges were giving her feedback.
4. Swine flu fiasco.
Remember in 2009 when a swine flu outbreak was all over the news? Well, the H1N1 virus didn't escape the ballroom. During season nine of DWTS, Derek Hough was reportedly the first to come down with the infection. It wasn't long before it was passed on to others, including fellow dancers Mark Ballas and Lacey Schwimmer.
5. Master P stepping in for Romeo Miller last minute.
Romeo was originally supposed to show off his dance skills during the show's second season, but had to withdraw from the competition when he injured himself while playing basketball just a few weeks ahead of the premiere. His dad, hip-hop legend Master P, stepped up to the plate last minute, but was harshly dubbed one of the worst contestants ever.
"My dad actually saved the day," Romeo later told the New York Daily News. "He's like, 'Look, I'll do this for you. When does the show start?' I'm like, 'Tomorrow.'"
Flash forward to season 12, and Romeo got a chance to compete in the ballroom with pro Chelsie Hightower, whom he kissed on the lips following a romantic waltz to "My Heart Will Go On."
"I was in character," Romeo said at the time. "I was feeling like Jack from Titanic."
6. Judge Bruno Tonioli taking his comments too far.
During season 11, singer Michael Bolton and his partner, Chelsie Hightower, performed a jive to Elvis Presley's "Hound Dog," poking fun at being in the doghouse for their low scores from the previous week.
"It was a doggie mess of a Jive," Tonioli, who gave the pair a score of 3 out of 10, said. "You did it all very, very, very badly. I think this is probably the worst Jive in 11 seasons."
Following his elimination, Bolton later told Good Morning America he was "disappointed with Bruno."
"To me, he let everybody down," he said. "My mom was there, she's 90, she flew down to see the show, and I just didn't expect that level of disrespect from him."
7. Kim Kardashian admitting she has trouble shaking her butt (and proving it on the show).
She may be known for showing off her voluptuous curves in public, but the reality star revealed she doesn't exactly know how to shake her booty during the show's seventh season.
"Everyone's gonna expect this, like, sexy thing and I'm really not," she confessed during a pre-taped interview package with pro partner Mark Ballas. "My biggest challenge with the mambo is just shaking my butt. Everyone thinks I know how and I just really don't. I think I need, like, Booty 101."
Unfortunately, her lack of skills resulted in her being the third contestant to be eliminated.
8. Cheryl Burke spilling ALL the tea.
Last April, the pro dancer had no problem dishing secrets about her fellow dancers and partners during an appearance on the Allegedly With Theo Von & Matthew Cole podcast.
First, she slammed her season four partner, Ian Ziering, whom she called her "least favorite" contestant to be paired with ever. "[Working with him] made me want to slit my wrists," she exclaimed.
Though she later apologized, saying her words were "out of line," the rest of the interview was equally juicy, opening up about behind-the-scenes hookups.
"I think we all dated each other at one point," she admitted about the dancing pros on the show. "All of us dancers, we've known each other -- [Maksim Chmerkovskiy], we've known each other since I was 12 and he was, like, maybe 15, I think he is three years older than me -- so ya know, things happen."
"He was a good kisser," she said about Chmerkovskiy, who is now engaged to and has a baby with fellow DWTS pro Peta Murgatroyd. "Maks is a good kisser."
9. Sasha Farber proposes to Emma Slater on live TV.
During the competition show's 23rd season, fans were in for a sweet surprise when Farber got down on one knee and asked his longtime girlfriend to marry him. The pair performed a group number together, which was followed by a commercial break. When the live show returned, host Tom Bergeron joined the couple onstage.
"First of all, you guys have great chemistry," he said. "And Sasha, I've always thought you had the potential to actually host. So I'm going to give the show over to you."
"I've been meaning to do this for such a long time," Farber said to Slater, as he pulled out a ring. "I love you so, so much."
10. Nick Carter confirms his wife is pregnant and learns the sex of their baby during DWTS.
Back in November 2015, rumors were swirling that the Backstreet Boys heartthrob and his wife, Lauren, were expecting their first child together. Not only did he confirm the news was true, but he also got emotional when he discovered the baby's gender on live TV.
After performing a stunning contemporary number to "I Can't Help Falling in Love With You" with Sharna Burgess, his wife joined him backstage for a mini reveal party with co-host Erin Andrews. When the two opened a gift-wrapped box, blue balloons floated into the air -- revealing their first child was a boy! Since Odin's arrival last April, the two haven't been able to stop gushing over their little bundle of joy.
11. Julianne Hough wearing barely nothing while dancing with… her brother?
Yeah, that happened! The DWTS pro-turned-judge was nearly nude, rocking a sheer bodysuit with red embellishments strategically placed over her private areas, for an upbeat performance to One Republic's "Love Runs Out." Hough was joined by all of the season 19 male pros for the steamy piece, including her sibling, Derek Hough.
