Listen to Carly Rae Jepsen Radio only on iHeartRadio

Carly Rae Jepsen was a star in Canada before 'Call Me Maybe' hit the airwaves in the U.S. of A., and she has Justin Bieber to thank for making her a star on this side of the border.

The song has become a huge hit - recently cracking the top 10 - and Justin Bieber's lip-dub video (along with famous friends Selena Gomez, Big Time Rush star Carlos Pena, Ashley Tisdale and more) has spawned lip-dub covers from the likes of Katy Perry and the Harvard University baseball team, to name a few.

In an interview with iHeartRadio, Carly Rae opens up about 'Call Me Maybe,' her reaction to the lip-dub videos, and her relationship with Bieber.  She even has a little fun on the phone with The Biebs along with iHeartRadio's own JJ and talks about the much buzzed-about collabo! Wonder if it will end up on Bieber's new album...
