Jennifer Lopez celebrated Thanksgiving on the island of Kauai, Hawaii, with her twins, other family members and her boyfriend Casper Smart.

But today it was all about one-on-one time for Jennifer Lopez, 42, and her toy-boy, Casper Smart, 24, as they cuddled up in a cabana.

Looking very much the couple, the scantily-clad pair cuddled and cavorted in the shade as the sun beat down outside.

An onlooker said: “He seemed very protective towards her, it was quite sweet… he seemed like the older one, they seemed if not love, well, very happy to be together.”

Jennifer Lopez was reportedly been seen frolicking on a beach with her three-year-old twins, Max and Emme.

Casper Smart, whose real-name is Beau Paul Smart, has tried to remain in the shadows, until today.

Casper Smart has had numerous run-ins with the law since 2004.

Most of the charges have been minor motoring misdemeanors relating to either speeding or driving without a valid license and failures to appear in court.

In one case he was pulled over by police for speeding on his motorbike at over 100mph.

The most recent offence committed in February 2010 could potentially land Casper Smart behind bars.

The charge relates to an “exhibition of speed” a section of the law more commonly known as street or drag racing.

Casper Smart, who was rumoured to have met Jennifer Lopez in May, pleaded no contest to the charge in March after an initial not guilty plea.

The dancer’s bail was set at $26,000 – and he is yet to be sentenced, according to the court records.

Casper Smart is due in court to be sentenced by a judge in Los Angels on January 5, 2012, and could face jail time as well as a stiff fine.

While he awaits his fate, Casper Smart has been busy with work commitments.

Last Sunday he performed alongside Jennifer Lopez at the American Music Awards in Los Angeles.
