After breaking things off with his longtime girlfriend, stylist Karolyn Pho, Shia LaBeouf has quickly moved on to dating his Nymphomaniac co-star Mia Goth.

The pair were spotted enjoying a trip to Starbucks in Los Angeles on Wednesday. Despite the seven year difference in their ages, LaBeouf has apparently already met 19 year-old Mia's parents.

"They've kept their relationship under wraps, but they pretty much started dating after he broke off things with Karolyn a few months ago... Shia and Karolyn had a volatile relationship and it came to a head just before he began filming Nymphomaniac," a source close to the actor said.

Shia and Karolyn are believed to have broken up largely in part of his role in Nymphomaniac, which he claimed will involve real sex scenes.
