Katy Perry has revealed that she and her fiance, British comedian Russell Brand, won't be living in the UK, as she has no intention of quitting sunny California for a British lifestyle when the couple get married later this year.

"We won't be moving to London anytime soon," she said. "I'm sure that Russell wants to keep his roots, he's English and likes being that dapper man so he's going to want to keep something here. But right now I'm clinging to California. It's because I'm a serotonin girl. That's why I live there. Like my serotonin level would fluctuate if the sun doesn't come out, my personality doesn't come out."

Perry recently revealed that she would love to collaborate with the singer Marina And The Diamonds.
