Splash NewsThings are heating up for Jennifer Lopez and her dancer beau Casper Smart.
So much so that the two spent Thanksgiving weekend at the St. Regis Princeville Resort in Kauai, Hawaii, with Lopez's 3-year-old twins, Max and Emme.
Smart was even photographed on the beach playing with the kids. At one point he lifted Emme and twirled her around in his arms.
A bikini-clad J. Lo, 42, and shirtless Smart, 24, also drank fruit cocktails at the poolside Trina Turk cabana on Saturday.
"Getting ready to go wakeboarding and ride some ATV's!!!!" Smart tweeted yesterday.
Later on, Lopez and Smart took a helicopter ride for some aerial sightseeing over Kauai.
As we were the first to tell you, the relationship isn't as casual as many have assumed. "It's pretty serious," a source said. "They're together a lot. She's never been happier."
The twosome jetted off for the tropical vacation just days after they showed some major PDA at Lopez's American Music Awards party at Greystone Manor in West Hollywood.
Lopez goes back to work later this week with a trip to Morocco to perform on Thursday at the opening of the Morocco Mall in Casablanca.
