Carly Rae Jepsen's mystery man, who she claims to have been dating for over a year, has been revealed as a fellow musician.

During a GetGlue HD launch party in New York, Jepsen was spotted holding hands with her boyfriend, who has yet to be identified until now. Sources said that Mathew Koma, a guest who also attended the party, introduced Jepsen as his girlfriend while at the soiree.

"He introduced her as his girlfriend," a source told People magazine. "He seemed really excited about it, and she was smiling from ear to ear by his side during the introduction. He seems like a really nice and personable guy."

Jepsen also enjoyed a dinner afterwards with Koma and her parents, where several people in the restaurant recognized the star.

"Many people recognized Carly and she posed for pictures with fans," an onlooker at the Lower East Side's Stanton Social told the magazine.

Koma is a musician on the same label as The Far East Movement and LMFAO. He is currently on the Cherrytree Pop Alternative Tour in the USA which began on May 22 in Ohio. Jepsen spoke about a boyfriend in the past but failed to indentify him as Koma.

"He makes me laugh every day and not always on purpose, but he's my guy," she told People magazine back in May. "He's been really amazing and very supportive."

Since the early summer interview, Jepsen appears to now be acting more publicly about her relationship. The couple was also spotted together last weekend leaving the Sunset Marquis, according to Mail Online. Jepsen informed fans on Twitter that she would be heading to Mexico after her night in New York. The singer is set to release a new record "Kiss" in September.
