New Couple Alert: Minka Kelly & Topher Grace

While John Mayer is traipsing about flaunting his new romance with Jennifer Aniston, his most-recent ex-girlfriend, actress Minka Kelly, doesn't appear to be brokenhearted. In fact, witnesses tell OK! that the raven-haired beauty has found herself a new man — actor Topher Grace!

According to witnesses at Stonefire Pizza Co. in L.A., Minka and Topher, two of Hollywood's oddest-named celebs, were being extremely affectionate with each other, and looked like they wanted to make out Thursday night as they shared a pie.

So was their meeting a romantic rendevous, or just dinner among friends?

A rep for Minka denies reports of a budding romance saying, "She Minka is not dating Topher Grace.  They were at Stonefire Pizza, however they are just friends."
