Russell Brand has revealed why he and Katy Perry's marriage was so short-lived. The actor told Esquire magazine, "Some of it's the fame, but I think getting married is - you've got a whole other person that you've got to make as important as you. I live a life where I have a lot of freedom, so if I meet someone and I go, 'Right let's be onogamous,' that's a f**king change. But I tried it and I loved it. I really think she's a lovely beautiful person [Katy Perry]. It's just hard isn't it? She's got a lot of options, I've got a lot of options, so you've got to really, really want it."Brand admitted that their failed marriage may be due to his temptation for other women. He said, "I've given over too much of my life to its pursuit. And I've probably harmed other people, by being selfish. And really, I'd like to be married. I'm just not transmitting that frequency of 'Soulmate! Soulmate!' I'm transmitting the frequency of "Mmm!"
