Taylor Lautner has been craving the sweet stuff.

The 17-year-old actor, who plays werewolf Jacob Black in The Twilight Saga: New Moon, has had to cut out sugary treats in order to bulk up for the role. “I really miss ice cream. My favorite flavor is actually cake batter. It’s really good but I can’t have it. It’s torture,” he said.

But despite all his hard work, Taylor recently revealed that he is “embarrassed” by the publicity photos. The actor posed topless in promotional pictures and admitted he didn’t want his family to see the images. “It’s embarrassing for me. And I’m sure it’s awkward for all of them. I’m hoping that I don’t get teased by my family because I’ll start blushing,” Lautner stated.

Taylor also spoke of his horror when an older female fan tried to remove her underwear in front of him so he could autograph them. “I had this 40-year-old woman trying to find a way to take her panties off for me to sign them. They had my name imprinted on them. So that was kind of strange,” he recalled.

New Moon opens in theaters on November 20.
