Robert Pattinson jealous of Taylor Lautner's muscles

London (ANI): Actor Robert Pattinson has admitted that he is jealous of Twilight co-star Taylor Lautner's muscles. Pattinson, who is now starring with Lautner in the vampire sequel New Moon, said that he was taken aback by seeing his co-star"s pumped up body.

"It was incredibly annoying when I saw Taylor's transformation," the Sun quoted Robert as saying.

"I realised just having a pre-pubescent girl's body wasn't going to work for me any more. In fact I saw him and thought Jesus, I'm going to get fired," he added.

Inspired from Lautner, the British heartthrob hit the gym too and it's paying dividends - especially in America where the Twilight sequel is shattering box office records.
