Love is more than a maybe
for Carly Rae Jepsen
and Matthew Koma.
The "Call Me Maybe" singer, 26, has been dating the musician
, a sources tell PEOPLE.
"He introduced her as his girlfriend," a source told PEOPLE. "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."
The couple was also spotted holding hands in the lobby by a party guest at the GetGlue HD Launch Party at the Standard, East Village in New York City.
Later, the singer stepped out with Koma for dinner at The Stanton Social, says a source.
"Many people recognized Carly and she posed for pictures with fans," an onlooker at the Lower East Side eatery says.
In May, Jepsen gushed to PEOPLE about a beau she declined to identify, but it turns out that wasn't Koma. She was referring to a previous boyfriend.
While Koma is featured
on the electronic dance hit, "Spectrum" by Zedd, rock 'n' roll dominates on his debut EP, Parachute
