Carly Rae Jepsen need not worry about anyone calling her, maybe. She's actually already in a relationship.

The singer has reportedly been dating Cherry Tree recording artist Matthew Koma for over a year. The pair were spotted together, holding hands, at the GetGlue HD Launch Party in New York City over the weekend.

"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."
