Since 'Call Me Maybe' is probably stuck in your head anyway, aren't you sort of wondering who inspired Carly Rae Jepsen to write the catchiest song ever? It looks like we may have found our -- er, her -- man!

The 'Good Time' songstress is dating musician Matthew Koma, and they've been together for about a year. And uh, how cute is he?!

Jepsen has spoken about her boyfriend previously, but she's been vague about his identity. Back in May, the Canadian cutie told PEOPLE, "He makes me laugh every day and not always on purpose, but he's my guy. He's been really amazing and very supportive."

However, PEOPLE's sources spotted the couple out and about, and they were super cute together, so now we know a little more about him. "He introduced her as his girlfriend," a source dished. "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." Aww!
