Sunday at TAO Beach saw reality star and Vegas show headliner Holly Madison hosting for the day. Madison arrived in jean shorts, a t-shirt and knee high tennis socks but quickly shed her outerwear to reveal a black bikini. The blond bombshell walked around TAO Beach, happily posing with fans for photos and even popped into the pool to cool off. Sushi rolls and fruit were served in her cabana as Madison and friends relaxed and soaked up the rays.
