Jennifer Lopez and backup dancer Casper Smart spent a romantic Thanksgiving holiday together in Hawaii, further fueling rumors that they are dating.

Photos emerged on sites like Us Weekly, of the pair sipping tropical drinks in their swimsuits on the island of Kauai. 24-year-old Smart was also spotted playing with Lopez's 3-year-old twins Max and Emme during the trip.

"Casper was great with the kids," a source told Us Weekly. "[He] was twirling them around and doing flips with Emme and she seemed very comfortable with him."

The pair sparked relationship rumors earlier in the month and were spotted getting cozy after their performance at the American Music Awards (pictured above together).

"Yes, they are dating and having a good time," a source told People magazine earlier in the month. "They've been getting more open with their flirting for weeks."

But just because Lopez is dating, doesn't mean she's making any long term plans, another source told People that Lopez considers Smart to be a "fun fling" and believes, "It's not meant to turn into anything more."

Smart was a backup dancer in Lopez's performance on "American Idol" in May (pictured above) and has also performed in films like "Honey 2," "Step Up 3D" and "Dance Flick" and on television series like "Glee" and "How I Met Your Mother."

According to his Facebook profile, Smart has also performed backup for Beyonce, Pink, Eminem, Sean Paul, Toni Braxton and Jordin Sparks.

Lopez announced her split from husband Marc Anthony in July. Lopez, 42, and Anthony, 43, did not specify a reason for the split. The two married in June 2004 and their twin son and daughter, Max and Emme, were born in February 2008.

Lopez has been married twice before but has no other children other than her and Anthony's twins. She was married to Ojani Noa between 1997 and 1998. Lopez also wed actor and dance choreographer Cris Judd in 2001. They divorced in 2003.

Lopez recently finished filming "What To Expect When You're Expecting," which stars Cameron Diaz. She will also return as a judge on "American Idol" when the music competition returns for its eleventh season.
