HollywoodLife.com spotted The Hills cutie partying at the Tao Super Bowl party at Wall nightclub inside the W Hotel South Beach on Feb. 5, where she was seriously trying to get close to the Yankee slugger. Kristin, who was definitely enjoying the cocktails and Pop Chips that were being served in the VIP area, was doing everything in her power to get to the table that Derek was sitting at with he fellow team mate Alex Rodriguez, 34!
