Marc Anthony

Marc Anthony didn't waste time when it came to showing the world that he'd moved on from his July 2011 split with the multi-talented Jennifer Lopez. By New Year's, while J.Lo was off with her new boy toy Casper Smart, Anthony, 43, had cozied up to Venezuelan model Shannon De Lima, 24. And he made sure everyone knew about it! He even sent his new lady love a more modern version of the love letter – a Spanish tweet which when translated into English means, "To Shannon, my statue of liberty. Kisses baby!" The singer then went on to post a pic of he and De Lima kissing on his Facebook page. OK, Marc, you're dating again, we get it!
