OK, so they've only been together for a month or so, but already the celebrity rumour mill is claiming that Russell Brand and Katy Perry might be about to tie the knot.

A source close to sex-mad funnyman Russell has been quoted as saying: "We've never seen him like this. He always has a woman on his arm, or in his bed, and hasn't been interested in monogamy.

"But this is different - we all think it won't be long before he marries Katy. I'm waiting for a call to say they are in that Little Chapel in Vegas and have run off to get married."

Not much in itself perhaps, but Russell himself (sort of) added fuel to the fire in an interview with the Sunday Times last weekend, in which he confessed that Katy had changed his life and even mentioned children.

He said: "Katy's lovely. I am living in a different way at the moment. Regardless of what happens in my current situation, I am unlikely to be satisfied with the calamitous promiscuity of the preceding five or six years.

"I am ready for children actually. It's been seven years since I took drugs. I've made a film. I don't have to fight so much. I've grown weary of the carousel."
