According to Us Weekly, the show (starring AnnaLynne McCord, Shenae Grimes, Matt Lanter, Jessica Stroup and Jessica Lowndes) has been canceled due to meager ratings.
The show has reportedly averaged 1.23 million viewers this season, being overshadowed by new hits The Vampire Diaries and Arrow.
"The CW has had five great seasons with America's favorite zip code, 90210," CW network president Mark Pedowitz announced in a statement. "I'd like to thank the talented cast, producers, and crew for all their hard work and dedication to the series. We are very proud of the West Beverly High alumni."
