Russell Brand: ‘Incompatibility’ Led to Katy Perry Split

Jeffrey Mayer/WireImage(SYDNEY) -- Ever since Russell Brand and Katy Perry’s very public divorce in December, the former heroin addict turned movie star has slowly been opening up about what exactly caused the split with the “Fireworks” singer.

“Sometimes it goes well, sometimes it don’t,” Brand told Australia’s 60 Minutes about the relationship.  “But if you sort of sense there’s an incompatibility, then in any relationship regardless of the status of the individual, it kind of is best to go separate ways.”

Brand also hinted that he and Perry had little interests in common.  Reports after the split stated Perry’s partying and reluctance to have a baby right away may have been a contributing factor.

“I think if you’re someone who’s really into mountain biking, it would be good to go out with someone else who’s into mountain biking, and if you’re really into Eastern mysticism, go out with someone else who into Eastern mysticism,” Brand said.  “I think if you’re a devoted tennis professional and you get married to a crystal meth addict, you might have trouble.  I’ve been in a lot of trouble.”

Brand and Perry married in India in 2010, but 14 months later Brand filed for divorce.  Their divorce was finalized in July.  Perry chronicled much of the split in her documentary Part of Me.

“I thought it would have been strange if I had completely avoided it, because it’s, sometimes, you know, when there’s a problem, it’s not about the problem, it’s how you solve it.  And you can’t avoid an elephant in the room, of course,” Perry told ABC News’ Elizabeth Vargas in July.

“But I wanted to be very diligent and respectful about it.  And hopefully, you know, people see that problem and they see me having that problem, they’re like, ‘Oh.  Well, even she can’t dodge life’s curve balls.  Even at that level.’  And they can relate to me better.  That’s what I want is, I want that human connection, especially with my fans,” she said.
