Christopher Knight, 47, the actor who played Peter Brady on the Brady Bunch, had turned into a fat blob of a slob by 2003 when he took the Discovery Health's Celebrity BodyChallenge in 2003 and whipped himself more or less into shape. On the set of 'The Surreal Life' this past fall he met Adrianne Curry, 22, from 'America's Next Top Model.' They plan to marry. Speaking of the 25-year age difference, Adrianne says: "He forgets what it's like to have fun sometimes," whereas he says "The sex is really good. She has outstanding energy and life to her. It's all I can do to keep up!" If a reader has Chris Knight's e-mail, please send him a message about Cialis. (By Scott Rose)
