Funnyman RUSSELL BRAND has declared his love for KATY PERRY, just days after the couple was first spotted stepping out together.

The singer was seen walking arm-in-arm with Brand in London on Friday after they reportedly enjoyed a romantic break together in Thailand last month.

Katy has since headed to France for Paris Fashion Week - and the Forgetting Sarah Marshall star is missing his new lover.

He tells Britain's The Sun newspaper, "I think I'm in love."

But he refused to comment on his time spent with Perry adding, "I don't think I should be drawn on that."
