Robert Pattinson's six pack quest

The actor tried to buff up for Twilight scene

Pattinson's admitted he tried to get a six pack for scenes in the vampire saga in which he was required to be shirtless.

The British actor was inspired to get fit by Twilight co-star Taylor Lautner who famously changed his physique from boyish to muscly to show his character's development from teen to man.

Pattinson wanted to look fit for the honeymoon scenes between Edward and Bella, played by real life girlfriend Kristen Stewart.

"I worked out for six months" said the 25 year old "After filming the sex scene, the first thing I thought was 'Time to eat! I ate ice-cream and cake. I took a few days from working out, that was a true celebration".
