22 of the Messiest Celebrity Breakups Ever

Heard started off as the bad guy here, filing for divorce a few days after Depp's mother passed away. But with reports surfacing of the years of abuse she endured from him, this sad, awful mess is only beginning.

She reportedly cheated on him after three years of dating, making him cry a river. And write songs about their split.

Their relationship came to a violent and public end after she was left with a black-and-blue face and bite marks. They broke up, found their way back together, but then split for good. Phew.

They were unhappy for years but stayed together so as not to disappoint the public. But Diana had had enough, and could no longer deal with Charles' alleged affair with now-wife, Camilla Parker-Bowles, telling the BBC in a 1995 interview, "There were three in the marriage, so it was a bit crowded." Ouch. Sadly, she died a year after their divorce.

They may be beautiful but their split was about as ugly as it gets, with their custody battle over Nahla escalating over the years. They've managed to figure out how to co-parent their daughter but there's no love lost here.

Just days after Sandy won an Oscar in 2010, Jesse ruined what should have been a beautiful time by issuing a public apology for cheating on her with multiple women. He not only broke her heart but ours too. Because you just don't do that to America's sweetheart!

Their split was pretty bad — and all caught on camera for The Real Housewives of Beverly Hills. What made it all worse? Kelsey marrying Kayte Walsh a mere two weeks after his divorce from Camille was finalized. Ugh.

She gets along great with ex-husband Bruce Willis, but that's because he didn't cheat on her like Kutcher did.

He supposedly cheated with a hairstylist and while she's admitted she's tired of it, their daughter Kelly retaliated by tweeting out the mistress' phone number. Do you scold or praise her?

He's called her every name in his made-up vocabulary, from "traitor" to "loser whore,"and screamed so many death threats, she had to get a restraining order. They made peace at one point, but the name-calling picked up again. Not sure where they're at now.

Their 2002 divorce and ensuing custody battle was epic, particularly the infamous voicemail he left for their daughter Ireland. It doesn't get nastier than that.

Actually, hold that thought. It DOES get even more nasty. After photos of Saatchi choking Lawson went viral, she filed for divorce. And he fought back even dirtier, insituating she was also violent with him and accused her of being a drug addict. Disgusting.

Their split seemed quite amicable, what with smiley faces on the divorce papers (from her) and Brand waiving his right to a trial, and not going after Katy's money (which he could have since there was no pre-nup). But it was post-divorce, what with her documentary Part Of Me painting her as the only one trying to save their marriage, not to mention her song "Wide Awake," and Rusty cracking the odd joke about his ex during interviews, and let's just say they're no longer friendly.

Eddie and LeAnn met on the set of a Lifetime movie, cheated on their respective spouses, divorced them and are now married to one another. One word: karma.

So much drama with these two including a custody battle, restraining orders, domestic abuse allegations and harassing voicemails. She tried to take him to the cleaners but Gibson's crack legal team saved his bacon and she left with barely anything. Probably not what she had in mind but at least she's out.

There was something so sweet about these two — that is, until 2011 when news came out that Arnie had fathered a child with a member of his household staff. While Shriver was pregnant with their youngest son, Christopher. Ick.

The golfer was living the dream, what with a great career, beautiful wife and two healthy kids. But that all came crashing down in 2012 when he admitted he cheated on Nordegren with multiple women. They divorced later that year and his golf game hasn't been the same since.

In one of the quickest divorces in history (especially when you factor in all his money and their daughter, Suri), TomKat reached a settlement a mere 11 days after Holmes blindsided Cruise with divorce papers. Katie likely could've gotten more had the case gone to trial but since they settled so quickly, it must've been pretty bad for her to want out so fast.

Their breakup not only affected them but Twihards everywhere. Sparkles was devastated when photos of K-Stew and her married-with-kids Snow White and the Huntsman director, Sanders, doing way more than canoodling were published. Rob later took her back but the damage was done and they eventually split for good. As for Sanders and Ross, they divorced and she has since remarried, exchanging vows with record producer Jimmy Iovine earlier this year.

The golden couple shocked the world when they broke up, especially upon learning that Brad seemed to have cheated on Jen with his Mr. and Mrs. Smith co-star, Angelina Jolie, resulting on everyone picking sides — Team Jen or Team Angie.
