Matthew Koma can call Carly Rae Jepsen at any time. Definitely.
That's because the musician is dating the 26-year old Canadian star, as witnesses confirm to People Koma and Kepsen went public at the GetGlue HD Launch Party at the Standard, East Village in New York City this week.
"He introduced her as his girlfriend," a source said of Koma. "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."
Koma is mostly a rock 'n' roll artist and has released a debut EP titled "Parachute." He has been dating Carly Rae for more than a year.
Jepsen, meanwhile, will release a new album on September 18.
