There might be a wedding in the air for Russell Brand and Katy Perry, or at least there's massive speculation about it. Brand went shopping for a diamond ring on Friday.

The funnyman has been dating Perry since October after they met at the MTV Video Music Awards the previous month.

He has spoken frequently of his deep feelings for the I Kissed A Girl hitmaker, recently admitting: "I am in love."

And he's now fuelled rumours he is about to pop the question, after he was photographed browsing diamond rings at top London jewellers Cartier.

An onlooker tells Britain's News of the World newspaper, "His face lit up when he saw this one diamond ring. He put it on his hand and he just gazed at it for ages, deep in contemplation."
