Why Jennifer Lopez Went Cougar With Casper Smart

At 24, backup dancer/beau Casper Smart is barely half Jennifer Lopez's age — enough enough to be her son — and the 42-year-old is flaunting it in the 43-year-old estranged husband Marc Anthony's face, from one side of the world to the other.

Over Thanksgiving, J.Lo and Casper took a PDA-packed trip to spend the holiday with her family in Kauai, Hawaii — where he frolicked on the beach with her toddler twins, Max and Emme. Then, last week, the singer (whose second husband, Chris Judd, was also a chorus boy) brought her new love to Casablanca, Morocco, where she performed for the royal family at the launch of a new shopping mall.

"Jennifer knows people are calling her a cougar, but she doesn't care," a source tells OK!. "Casper makes her feel sexier than she's felt in years. The fact that he's so much younger is a little bit about revenge. She loves that Marc knows she's with a guy have his age.

"But the bigger picture with Casper is how he makes her feel," that inside source adds. "She's totally carefree and has her lust for life back."
