Jennifer Lopez turns up at the Catchphrase studio to tell Carol Vorderman she wants her ass back!

Rumour has it that Jennifer Lopez was in a foul mood this week after finding out that someone had stolen her backside and was flashing it around willy-nilly on ITV game show Catchphrase. J-Lo must have been seething when she spotted this picture of Carol Vorderman turning up at the studios...

I know she's in her 50s, and she's a maths geek, and she was pretty dowdy in those early Countdown years... But you would wouldn't you?
