Is Zac Efron gonna get it on with a smokin' hot older woman?

We've got our fingers-crossed for this cougar action.

Efron has finally confirmed he has joined the star-studded ensemble cast of New Year's Eve, Garry Marshall's follow up to his hit, Valentine's Day. "I can tell you that all my scenes are with Michelle Pfeiffer," he told me at the Golden Globes. "I'm very excited."

So will we see him locking lips with the 53-year-old stunner? "I'm not gonna say," he teased.

Trio will join all-star ensemble that includes Robert De Niro, Michelle Pfeiffer, Hilary Swank and Ashton Kutcher.

Sarah Jessica Parker is set to join New Line's New Year's Eve, while Halle Berry, fresh off her Golden Globe nomination for Frankie and Alice, and Zac Efron are in negotiations to also join the all-star cast.

The trio will join an ensemble that includes such names as Robert De Niro, Michelle Pfeiffer, Hilary Swank, Ashton Kutcher, Sofia Vergara, Jessica Biel, Lea Michele and Abigail Breslin, all of whom who are in various stages of negotiations for roles as well.

The movie tells intertwining stories of a group of New Yorkers as they navigate their way through bittersweet drama and romance over the course of New Year's Eve.

Parker is playing Breslin’s mom, someone who relies too much on her daughter for company.

If a deal makes, Berry will play a caterer who runs into a former flame. Efron is on track to play a bike messenger who ends up trying to fulfill Pfeiffer’s New Year’s Eve resolutions in exchange for tickets to a big party.

Mike Karz and Wayne Rice are producing.
