Alec Baldwin, 53, Dating Twentysomething Yoga Teacher

Alec Baldwin is "smitten" with a 2007 NYU graduate, sources tell the New York Post's Page Six.

The "30 Rock" star, 53, has been dating 28-year- old Yoga Vida studio director Hilaria Thomas.

The two were photographed together at Carnegie Hall's 120th anniversary after-party last month at The Plaza.

"He's really into her," a source said. "He's taking her to the Tonys."

But Thomas wasn't pleased to get a call from us.

"I'm not going to answer these questions," she snapped.

Baldwin's rep joked, "He's actually been dating Russell Brand down in South Florida."

Ba dum bum.
