WhO Is MiLeY CyRuS's NeW GuY?

Miley Cyrus has been hanging out with a new guy – and he’s already met her parents.

On Sunday, Justin Gaston, a model and aspiring country singer, attended church in Pasadena, Calif., with the Hannah Montana star and her family. Later that night, he hit Disney’s Concert for Hope where Cyrus performed with the Jonas Brothers and Demi Lovato.

According to Cyrus's rep, Gaston, 20, is "a friend from Nashville." He met Cyrus, 15, earlier this year when he was a contestant on Nashville Star, hosted by her father, Billy Ray. Adds Gaston’s rep, Allen Osborne, “He's visiting L.A. for the week.”

A source close to Miley says, "They've been spending a lot of time together while he's in town."

The Pinesville, La., native has modeled for Kenneth Cole and Guess, and before he was eliminated in week three of Nashville Star he told PEOPLE of his music, "My style isn't like anyone else. If John Mayer was to meet Brad Paisley and they reproduced, that would be me."

These days, Gaston stars as Taylor Swift's Romeo in her new video for the single "Love Story." The two also met on Nashville Star and, "became good friends," Osborne adds.

Miley may want to take note: According to Osborne, Gaston has "had a 'crush' on Taylor Swift for quite a while."
