Jennifer Lopez and Casper Smart's Hawaii Vacation-With Her Kids!

And they said it wouldn't last. Jennifer Lopez has been spotted vacationing in St. Regis Princeville Resort in Kauai, Hawaii with her adorable twins, Emme and Max, as well as rumoured boyfriend, Casper Smart.

The two have been seen sitting pool side, drinking fruit cocktails and having fun. At one point, Smart even played with Emme, lifting her up and twirling her in his arms. He tweeted some of his activities (wakeboarding and riding ATVs) Sunday, Nov. 28. Lopez, 42, and Smart, 24, also reportedly went sightseeing by helicopter.

The pair must've gone to their tropical getaway immediately after being seen at the Greystone Manor in West Hollywood. They were there for the American Music awards and might have done a bit of PDA.

Recently, more information has come to light about Smart, a man who was once only known as J'Lo's mystery man. For one thing, he's actually an established dancer; he's performed with Beyonce, Nicki Minaj, Eminem and Jordin Sparks.

For eagle eyed fans, he can also be spotted in Glee where he's appeared in at least 3 episodes.

The most impressive thing on Smart's Resume? Remember 2008's viral video of President Barrack Obama and John McCain having a dance off? Smart was actually the body where McCain's head was superimposed on making his body (and dancing) famous to close to 12 million viewers.

Friends of Lopez say that the couple are happy and that Smart seems to have the purest of intentions.

"He's not jaded. He's not asking Jennifer to buy him this or that. He's courting her, like sending her flowers. I think his intentions are in the right place," the source said.

The vacation is set to end later this week though as Lopez is scheduled to be in Morocco on Thursday. Lopez will be at Casablanca at the opening of the Morocco Mall.
