The 90210 Season 5 premiere won't simply feature the return of Lori Loughlin as Debbie.

It will also deliver the latest in a very long line of musical performances on this CW drama, as Carly Rae Jepsen stops by to perform a pair of singles, neither of which will be "Call Me Maybe."

In anticipation of that fun cameo, the network has released a new promo based around the artist's "Good Time" and depicting fresh footage from episodes to come, including Max and Naomi getting into a car accident and Teddy considering Silver's unusual baby request.

Check it out now and look for Amber Stevens to also play a role on 90210 this fall.
