London:  Comedian Russell Brand has reportedly filed for divorce from Katy Perry because he wanted to start a family with the singer, but she was not interested.

Brand married Perry in India in 2010, and on Dec 30, 2011, the couple announced that they're getting divorced after 14 months of being married.

"I don't think Katy (Perry) really understood what marriage was about. I don't think she was prepared to give up her career. This wasn't one of those occasions when Russell (Brand) was mucking about, he wanted to settle down and have a family," a website quoted a source as saying.

"I don't think that's what Katy wants. I think she's very confused. They've been speaking a lot. There have been a lot of phone calls this week. Katy is 27...She's just done a year-long tour, she's incredibly successful and she wasn't ready to give up her career. I don't think she was prepared to give that up and give time to the marriage," the source added.
