Carly Rae Jepsen to Perform on ’90210′ Season Premiere

Canadian singer Carly Rae Jepsen will be hitting the season premiere of the CW's 90210.

The "Call Me Maybe" singer will perform a song from her new album in the Oct. 8 episode, where she will act as the headliner for Adrianna's (Jessica Lowndes) Las Vegas premiere, which is interrupted when Adrianna gets devastating news about Dixon (Tristan Wilds).

Jepsen, whose "Call Me Maybe" has been No. 1 on the Billboard Hot 100 for four straight weeks, will tour with Justin Bieber as a special guest during his North American trek.
