John Mayer's most-recent ex-girlfriend, Minka Kelly, doesn't appear to be brokenhearted over Mayer's new romance with Jennifer Aniston. The actress seems to have found herself a replacement to John, Topher Grace. The two were spotted being extremely affectionate with each other Thursday night as they shared a pie at Stonefire Pizza Co. in LA. However, Minka's rep denies the reports saying: "She [Minka] is not dating Topher Grace. They were at Stonefire Pizza, however they are just friends."
