Jennifer Lopez can't keep her hands off toyboy Casper Smart at celebrity football match

The American Idol judge hugged, kissed and even perched on her lover's knee at a celebrity football match in Puerto Rico on Saturday rather than getting down on her haunches like the rest of the gang.
Jennifer put decorum aside between her last two Dance Again tour concerts to get down and dirty with the Puerto Rican reggae duo Wisin y Yandel at Hiram Bithorn Stadium.

She showed wild enthusiasm between canoodling with her toyboy and was seen manically cheering as well as showing the boys how it's done by executing a few decent throws of her own.
Casper, 25, was of course on Team JLo, looking dashing in his red jersey with the sleeves rolled up to show off his glorious muscles and tattoos.
Wearing her straight brown hair in a high ponytail, Jennifer kept her aviator shades on even while posing for pictures with her team and opposition.

Jennifer looked tough and smirked through the photo session while balancing her bum precariously on Casper's skinny left knee.
At times, she seemed in danger of sliding off and perhaps that was the real reason behind the annoyed look.
She tried hard to keep her feet firmly braced on the green turf to keep from falling over.

As the only female in the group, Jennifer was the center of attention.
Her four-year-old twins Emme and Max were also there to join in on the fun and at one point the little girl could be seen scooped up in Casper's arms.
While most of the guys stayed within the lines of decency, one black-clad member of the opposing team seemed stuck on making an obscene gesture, which Jennifer didn't miss.

The match was in aid of Hurricane Sandy victims.
On Friday night, Jennifer was regal in blue as she took to the stage in Puerto Rico with her ex-husband, Marc Anthony, to sing their duet No me Ames (Do Not Love Me).
Jennifer wore a flowing powder-blue gown with plunging neckline while Marc opted for an all-black suit.
The couple, who are parents to four-year-old twins Emme and Maximilian, are still friendly despite splitting in July 2011 after seven years of marriage
