More deets on the Beverly Hills 90210 spin off!!! Lori Laughlin, aka Aunt Becky, is joining the cast as Celia Mills, wife of Beverly Hills High’s new principal, and mother to Annie, a role that Hilary Duff was has been approached to play!  Highly doubtful that the Duff will sign on but Lori is a go!  Full House meets 90210?!  I think my head is going to explode!
