Michelle Trachtenberg Looks Up To Zac Efron As Her...

Michelle Trachtenberg was off fighting vampires when she was 17 — but for “Seventeen Again,” she’s happy to be “free and clear” from action scenes, especially those that involve dancing. That, she leaves to her co-star Zac Effron.

“I just watch him and mope,” she said — and not because she’s pining for a different sort of action. As if! He’s playing her dad (even though she’s two years older), and just to rub it in, she called him “Dad” on set. “Anything we did, father/daughter-wise,” Trachtenberg told us, “I’d tease him, ‘I’m older than you! You’re not really my father,’ while he’s trying to tell me what to do.” But she understands that the girls love Zac, and she doesn’t fault them for that: “If you think he’s hot, rock on. He is.”

As for her own hotness, Michelle thinks the teen roles are going by the wayside real soon — well, at least after she’s done with her guest stint on “Gossip Girl.” “I got a few laugh lines now and crow’s feet and I’m sagging all over the place,” she laughed, “so I guess I can’t play a sixteen-year-old anymore.”

Are you excited to see Zac and Michelle to the father/daughter thing in “Seventeen Again”?
