London, Nov 7 'Twilight' star Taylor Lautner struggled to pile on weight for forthcoming sequel - because he hated having to eat every couple of hours.

The 17-year-old actor modified his diet and increased his exercise regime to transform his slim physique into a buff build.

Lautner was allowed to eat anything and everything in preparation for the role, but he insists it wasn't as fun as it sounds.

"Most people were like, that sounds amazing, to be able to eat all the time, and it is at first. But after a year and a half of it, I mean, I have to put something in my mouth every two hours, so it becomes kind of annoying!" the Daily Express quoted him as telling America's Star magazine.

Meanwhile, the American actor has sparked off rumours that he is romancing country singer Taylor Swift after the two of them were seen together in Los Angeles. (ANI)
