Hugh Grant's Fatty Jibes To Renee

British star Hugh Grant has been teasing his Bridget Jones co-star Renee Zellweger about her weight gain for the role.

Joker Grant is playing cad Daniel Cleaver in movie sequel TThe Edge of Reason, and wasted no time on-set in ribbing the usually svelte Zellweger about her expanded frame.

A source says, "The minute he clapped eyes on Renee he hollered, 'My God, you're huge!' He's been carrying on with the fatty jibes ever since, but Renee laughs it off, saying at least she's supposed to be chunky.

"They giggle together like kids all the time. The other day, she left him an autographed pair of Bridget-style big underpants - only they were about 10 sizes bigger than the ones she wears."
