90210 star Lori Loughlin has spoken out to defend her young castmates on the new show from reports they're starving themselves to appear superslim onscreen.The actress, who plays mum to Shenae Grimes' character Annie, insists the show's sexy cast are all naturally thin with metabolisms that allow them to eat whatever they want and not gain weight.Loughlin tells In Touch magazine, "They are thin, but they've been thin since the day I met them. It's not like they got on the show and their weight just plummeted."Shenae is very petite; her frame doesn't even look like it could carry a lot of weight... I see them eating lunch and candy... These girls are young and their metabolisms are moving at light speed - they can eat whatever they want."
