Shia LaBeouf had a very public split earlier this year from longtime girlfriend, Karolyn Pho, after rumors circulated that Pho didn't approve of his "non-simulated" sex scenes in the film "Nymphomaniac."

LaBeouf, 26, has been seen out his movie costar, Mia Goth, 19, and the actor hasn't appeared self-conscious about showing her affection. The couple reportedly got to know each other while filming the Lars von Trier-directed film.  The movie, which is scheduled for release in May, is Goth's first credited acting role.

"They've kept their relationship under wraps, but they pretty much started dating after he broke off things with [Karolyn Pho ]a few months ago," a source told Radar Online. "He got to know Mia on set and quickly became enamored of her. They have similar interests, they love alternative music, thrift stores and she is edgy and funny, which Shia loves."

The pair were first spotted going into a Los Angeles Starbucks together, the day before Thanksgiving. Although they have only been dating one month, Radar Online said LaBeouf has already traveled to London to meet Goth's family.

“They’re already spending a lot of time together, not just with work, but also have been hitting the town,” the source said. “Mia has made Shia very happy and he’s certainly found a party buddy for the time being.”

LaBeouf and Pho ended their relationship over the summer, after onlookers photographed Pho crying during a fight on a Los Angeles street.
