Robert Pattinson's shirtless scenes may have been grabbing all the headlines – but he's not the only Twilight star who gets to strip off in New Moon.

Taylor Lautner has revealed that he was required to do a bit of naked acting as Jacob Black, Bella's human friend who learns that he can transform into a werewolf.

“I was shirtless, all I was wearing was shorts,” he told Access Hollywood. “We were in 35-degree weather. [They] poured rain on [us], which is like so iced cold!

“And the scene was like four minutes long and I’m just sitting there and you can’t look cold.

“I’m the only one [in the buff], I’m just standing there like basically naked with everybody like bundled up in this ice cold weather!"

The 17-year-old bulked up to play the roll of Jacob, after initial speculation he would be replaced for the second movie instalment of the vampire saga.

And as you can see from the pictures above - taken from the recently released New Moon trailer - the chill appears not to have caused any muscle shrinkage!
