Things between Jennifer Lopez and Casper Smart are heating up fast.
The pair spent Thanksgiving together in Kauai, Hawaii, Us Weekly can confirm. Lopez brought her 3-year-old twins Max and Emme, who joined the lovebirds for an afternoon trip to the beach.
"Casper was great with the kids. He was twirling them around and doing flips with Emme and she seemed very comfortable with him," a source tells Us. "Jennifer got a chance to sit back and relax while Casper took over and played." According to Radar Online, Smart met several of Lopez's family members during the trip.
Lopez, 42, has tried to downplay her romance with the 24-year-old backup dancer, telling Ryan Seacrest: "Until I'm in a really serious relationship -- because of the babies -- I'm not really gonna be commenting on my personal life."
Though the "American Idol" host is reluctant to talk about her love life, she isn't afraid to show it. After performing at the American Music Awards on Sunday, a source witnessed Lopez "grinding in Smart's lap, giving him a kiss and rubbing his head" at Greystone Manor in West Hollywood.
