Amanda Bynes (What a Girl Wants, Big Fat Liar, The Amanda Show) will team up with Jennie Garth (Beverly Hills 90210) in this comedy about two young women who have pushed their sisterly relationship to the limits by becoming roommates. When 17-year-old live-wire Holly Tyler (Bynes) moved in with her strait-laced 29-year-old sister, Valerie (Garth), everything in Val's neatly regimented life changed. But it's not long before this odd couple realised that their support and respect for each other will get them through any crisis.
