robert pattinsonTwilight star Robert Pattinson has revealed he got a bit too into exercise while making the vampire movie.

The actor decided to get into shape for his inevitable new teen heartthrob role but he told Entertainment Weekly recently that he took it too far: “I used to go to the gym for about five hours a day but then I started losing so such weight.

“My head started to look really huge in comparison to the rest of my body.

“[Director Catherine Hardwicke] came up to me and said, ‘What are you doing to yourself?’.

“[To re-gain the weight,] I literally stopped exercising. Eating a cheeseburger after two-and-a-half months of doing that - it tasted like ambrosia.”
