Sometimes a kiss is just a kiss, and sometimes it's not. TMZ reports that one day after Marc Anthony kissed ex-wife Jennifer Lopez onstage at the Latin Grammys, he has separated from his wife Shannon De Lima after two years together. The couple do not share any children. This was Marc's fourth marriage. Oh, and in case you were wondering, J Lo's manager Benny Medina says that Marc and J Lo are "absolutely, categorically, 100% not back together."
