"Sometimes it goes well, sometimes it don't," Brand said during an interview with Australia's 60 Minutes. "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 went on to express that perhaps it's simply a good idea to just hook up with people who share similar interests as you.
"I think if you're someone who's really into mountain biking, it would be good to go out with someone who's into mountain biking, and if you're really into Eastern mysticism, go out with someone else who's into Eastern mysticism," he 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."
Earlier this year, Brand also spoke to Ellen DeGeneres about his 14-month marriage to Perry: "I still love her as a human being. She's such a beautiful human being, and I just have only love and positivity for her."
