Zac EfronIs heartthrob Zac Efron going after a Hollywood cougar? Well, sort of. But before panic strikes the teenage population, it should be clarified that it's just for his next movie role.

Efron has signed onto director Gary Marshall's 'Valentine's Day' follow-up, 'New Year's Eve,' according to E! Online. The actor teased his role in the star-studded ensemble cast at the Golden Globes earlier this week.

"I can tell you that all my scenes are with Michelle Pfeiffer," he said. "I'm very excited."

He's tight-lipped when it comes to just what kind of scenes he'll be sharing -- especially whether or not he'll be getting down with the 53-year-old actress in the flick.
