Olympic gold-winning skier Bode Miller was back to his bad-boy ways last weekend, hitting on lingerie-clad beauties at the Playboy Mansion. Miller made a beeline for former “Survivor” contestant Corinne Kaplan at Playboy Golf’s Pajamas & Lingerie Party at the Beverly Hills pleasure palace. Dressed in baby blue pajamas with a flap he opened to reveal his backside to giggling girls, Miller chatted up Kaplan, who quit her job as a pharmaceutical sales representative to appear on the 2008 season of “Survivor Gabon,” where she became known as a “self-proclaimed uber-bitch.” A spy told us, “Corinne looked gorgeous in lingerie. He was flirting with her all night. They were laughing and dancing, and the next thing you know they left together holding hands.” Also there was Post sex columnist and Playboy pin-up Ashley Dupre in a bathrobe on the arm of a mystery man. A rep for Bode declined to comment.
