No doubt, Jennifer Lopez, 42, enjoys basking in a hot guy’s attention again. But while it’s fun, it could be dangerous as well. “He wants to be rich and famous,” snipes an insider to In Touch about her new guy, Casper Smart, 24. “He’s a smooth talker and he obviously thinks J. Lo will be his meal ticket.” Compounding the problem, In Touch has learned Casper could soon be cooling his heels behind bars. He has a January court date to face charges for recklessly drag-racing a friend down an LA freeway last winter. And it doesn’t bode well that in 2006, he was found guilty for driving without a license. As a mom already responsible for 3-year-old twins Emme and Max, it looks like Jennifer might now have another child on her hands.
