Carly Rae Jepsen has been chosen as the opening act for Justin Bieber’s Believe tour.  But that’s not it for Jepsen. She’ll also take the stage to sing a duet with the Biebs!

In the newest issue of Billboard, the magazine states that the Canadian singers will be performing a song together at every single concert on the tour. The song that the two sing will be on Carly’s new album, Curiosity, which will be released in September. It may not be released as a single.

The pair’s manager, Scooter Braun, told Billboard, “We wanted Carly to stand on her own as an artist before she came out the door with Justin Bieber.”

Jepsen’s duet with Owl City, ‘Good Time,’ hit the  iTunes store today, but there may be a chance it won’t be featured on her album.
