I never got a phone call," he told Rolling Stone. "I was really caught off-guard, and it really humiliated me at a time when I'd already been dressed down. I mean, how would you feel if, at the lowest you've ever been, someone kicked you even lower?" Photo: Getty

John Mayer has a long list of famous exes and no qualms about talking about any of them. In an interview with Playboy, he addressed the generation gap between him and Jennifer Aniston. "One of the most significant differences between us was that I was tweeting. There was a rumor that I had been dumped because I was tweeting too much. That wasn't it, but that was a big difference. The brunt of her success came before TMZ and Twitter. I think she's still hoping it goes back to 1998," he said. Photo: Getty

During a performance in London, the comedian made a cringe-worthy joke about his sex life with ex-wife Katy Perry. “When I got divorced, I considered becoming a monk,” he reportedly said. “When you’re a monk, you’re not allowed to have sex with anyone. When you’re married, it’s one person. That’s one more than a monk. It’s not that different. I’d be having sex thinking, ‘Think of anyone, anyone else.’” Photo: Getty

Khloe Kardashian and Lamar Odom have split, but Khloe has nothing but respect for her ex. "Lamar is genuinely one of the best people I’ve ever met, and everyone says that when they meet him. I think Lamar’s gonna always be that person [for me] but that’s what made it so special," she told Complex in 2015. "Even if I had it for five years or whatever, it was the best ever and I’m grateful I did. Some people don’t get that ever and I had that magic for a long time." Photo: Getty

In an interview with GQ, Justin talked about his split with fellow pop star Britney Spears. "I felt like she had a couple of opportunities to just sort of stick up for me, and she didn't.

While Ben Affleck hasn't always said the nicest things about the state of his career when he dated Jennifer Lopez, he revealed in a Hollywood Reporter interview that they keep in touch and celebrate each other's successes. "We don't have the kind of relationship where she relies on me for advice, but we do have the kind of relationship where there'll be an e-mail saying, 'Oh, your movie looks great.' I remember when she got American Idol. I said, 'This was really smart. Good luck,'" he said. "I touch base," he said. "I respect her. I like her. She's put up with some stuff that was unfair in her life, and I'm really pleased to see her successful." Photo: Getty
