Now Jepsen hopes to carry all of that momentum through 2013 on the back of her latest single and upcoming US tour. "Tonight I'm Getting Over You," unlike "Call Me Maybe," doesn't carry the same bright-eyed optimism. Rather, the song describes the need to move on from a relationship gone bad, something all of us can relate to.

"Unfortunately, I'm pretty sure all of us can admit to that moment where there's been somebody who, you know, it didn't just totally work out or they didn't like you the way you wanted them to like you," says Jespen. "That's kinda what the song is about� coming to terms with that and then moving on and, you know, doing the classic� 'find somebody new.'"

Jepsen hammers home the reality of those feelings, adding "� it's brutal. It's the worst!"

And no, there is not one man out there responsible for putting her through this roller coaster of emotions. Jepsen's inspiration comes from the sum of all her experiences.
