Jennifer Lopez & Casper Smart

With their Florida getaway still in full effect, Jennifer Lopez made sure to hold her boy toy Casper Smart's hand to safely maneuver down Miami's Lincoln Road this weekend.

Boy toy extraordinaire Casper Smart is really cruising into Jennifer Lopez's life ... and rode around on a yacht with the pop icon and her two kids in Miami on Friday.

Banging Jennifer Lopez has some HUGE perks ... (besides just banging Jennifer Lopez) ... TMZ has learned her new boy toy is now driving around town in the pop star's pimped out BENTLEY!!!

Sources close to Casper Smart tell us ... the world's most famous backup dancer isn't just using the car to chauffeur his meal ticket around when she's in L.A. ... he gets the car for personal use too.

Besides car privileges ... dude has already flown across the world on a private jet ... gone on tropical vacations ... and as we previously mentioned, he gets to bang J.Lo.

Cris Judd ain't bitter that his ex-wife Jennifer Lopez found a younger, paler back-up dancer to mess around with ... dude tells TMZ he couldn't be happier for the pop star.

Judd married Lopez back in 2001 ... then divorced in 2002 ... and he's since re-married to a non-famous lady named Kelly A. Wolfe.

She's not officially divorced, but Jennifer Lopez is living the single life -- hitting up a raging Hollywood nightclub last night with her new boy toy Casper Smart ... TMZ has learned.

The couple stopped by Boulevard 3 -- and sources tell us, J.Lo and Smart partied all night in a private area of the club ... dancing with each other and being very affectionate.

Jennifer Lopez's 24-year-old backup dancer boyfriend Casper Smart is still living the high life -- hitching a private jet with his Latin cougar to fly from L.A. to Morocco this week.

Casper and his sugar mama of two are set to perform at a Moroccan mall -- but before they got down to business, they were spotted having a romantic dinner at a place called Rick's Cafe in Casablanca.

Jennifer Lopez's lips say she's moved on to new BF/dancer Casper Smart -- but at least one of her fingers seems to be holding on to her ex.

While J.Lo snuck a few cougar kisses with Casper between rehearsals in L.A. ... she was still sporting what looks a lot like the 8.2 carat wedding ring she got from Marc Anthony.

Why is Jennifer Lopez dating a ripped, 24-year-old backup dancer??? We're guessin' the answer lies somewhere below the belt.

Jennifer Lopez and her new boy toy BF Casper Smart continued their Thanksgiving weekend romp in Hawaii, cozying up on the beach this morning ... in the first photos of the couple since word of their relationship got out.

TMZ has obtained a photo of Jennifer Lopez with her new BF -- and backup dancer -- Casper Smart ... taken while they were traveling in Europe.

According to our sources, Lopez and Smart spent the first few months as "just friends" -- flirting, talking and just hanging out -- but lately they've been touchy-feely in front of JLo's other dancers.

We're told the mood of rehearsals has shifted -- she's a lot more focused on Casper ... who is 24. Jennifer is 42.

The photo was snapped in the summer when JLo was in Ukraine for a performance. Casper danced in the show, but we're told they were not dating at the time.

Jennifer's rep hasn't gotten back to us.

The guy at the center of the affair rumors is telenovela star William Levy -- aka the Cuban Brad Pitt -- who recently separated from his wife AFTER shooting the music video (see below) with Lopez.

But Levy's rep tells TMZ William and J.Lo are NOT an item ... saying, "The only relationship there was or is, is a professional relationship. That’s all there’s ever been.”
