Casper Smart, 24, has reportedly had the `American Idol` judge`s named etched onto his body in an area described as "somewhere below the belt" and the singer is said to "love" his new artwork. A source told In Touch Weekly magazine: "Jennifer thinks Casper`s tattoos are sexy, but this one is her favourite, for obvious reasons. She loves it, and she loves him." Jennifer - who has four-year-old twins Max and Emme with former husband Marc Anthony - recently praised Casper as a "good egg". She said: "He`s adorable. But you already see that. He`s a good egg. I don`t want to talk about it too much. It`s my private thing." Though she is happy with the dancer, the `On The Floor` hitmaker has admitted splitting with Marc was "really, really sad". She said: "Without going into detail ... it`s just really, really sad. "And look, we are still going through it, and it`s emotional sometimes and difficult. We`re still friends - and we`re parents. But it`s going to take time. It`s tough. "But for the most part, I feel very proud of the way we`re handling it. I really do. We are doing the best we can for the kids."
