90210 (and its predecessor, Beverly Hills, 90210) have always brought the hottest musical guests to the show to perform, so you could say Carly Rae has hit another huge milestone.
Of course, after her song Call Me Maybe went super huge, she became a hot commodity, and she's been traveling the world, doing interviews, making appearances and working on her new album.
You might say she's a busy girl.
The 90210 gig will be her first TV role--she'll play herself in the episode and perform a song from her upcoming album.
Look for Carly Rae on 90210 on October 8.
Meanwhile, Carly Rae is busy finishing up her debut album and will hook up with Justin Bieber as the opening act on his Believe tour, kicking off September 29.
Yep, Carly Rae is having a pretty good year!
