Rumors are swirling that Jennie Garth will be joining the Beverly Hills 90210 spin-off. Garth, who played Kelly Taylor, the popular blonde, recently dropped out of CBS’s upcoming comedy pilot My Best Friend’s Girl after the table read on Monday. She has been replaced by Kristin Booth. Us Weekly reports that it was “a mutual decision between her and the [CBS] producers” as Garth is still recovering from the loss of her father who passed away shortly after she was cast. According to the Hollywood Reporter, Rob Thomas, the writer of the 90210 spin-off, is looking to cast Garth as a fashion design teacher. Details about which other characters will make the transition to the new show are still unknown.
