Tori Spelling is hanging on to cheating, Dean McDermott for the kids’ sake. He’s checked his greedy, and ungrateful dingyness into rehab. Sources say Tori is just hanging on, in hopes that her new show, Mystery Girls, takes off. The Beverly Hills 90210 heiress has joined forces with her ex co star, Jenni Garth. ABC really took a gamble. The upcoming show is based off ‘Holly’ (Spelling), who is desperate to claim the fame she had in the 90s. Go figure.
