Lutz 'nervous about underwear pics'

Twilight star Kellan Lutz has revealed that he was initially apprehensive about posing in his underwear for a recent Calvin Klein campaign.

The actor, who plays Emmett Cullen in the vampire franchise, told NY Mag that he was nervous about the shoot but was put at ease when he arrived.

"I've never had to do anything like that, so in the beginning, I was just, like, 'So, is the temperature going to be hot? Do I need, you know, fluffers maybe?'" he explained.

"They made it really easy. The clothes fit great - there wasn't anything that was riding up, so you don't feel uncomfortable posing."

He added: "You know, the Twilight fans have been amazing with it. They really are a loving group of ladies."
