Russll Brand & Katy Perry movie costar?

Russll Brand and Katy Perry could be teaming up for a movie!

The couple announced their divorce over Christmas but remain firm friends and possible costars, according to sources.

“Russell has been working on a film script that he always intended would have he and Katie play the lead roles. He sees no reason why that can’t still happen,” says the source.

“He and Katy are parting on very good terms. They remain close and the prospect of them working together on something is very much alive.”

Recent reports claimed the couple’s marriage collapsed because he wanted children but he didn’t.

“I don’t think Katy really understood what marriage was about. I don’t think she was prepared to give up her career,” a source said.

“This wasn’t one of those occasions when Russell was mucking about, he wanted to settle down and have a family.

“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. That’s not too young to get married. But professionally she is in a very powerful position.

“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.

“It was reported she was taking a year off, but I don’t think she’s doing that. It’s very sad. Russell is very cut up about it all.

“It’s not great news. It is very raw and very recent. I don’t know what will come from this.”
