JENNIFER LOPEZ is furious that Marc Anthony is dating a 22-year-old hottie who’s filthy rich!

Marc’s new squeeze is blue-eyed beauty Chloe Green, an heiress to a British retail empire, and insiders say J.Lo, 43, is seething because Marc has one-upped her 25-year-old boy toy, back-up dancer Casper Smart.

“Jennifer always felt a certain pride in landing Casper, who looks young enough to be her son,” said an insider.

“But Marc believes he’s trumped her with Chloe, who at 22 is three years younger than Casper and incredibly rich to boot.”

Chloe – whose father is bil­lionaire businessman and Topshop owner Sir Philip Green – packed on the PDA with salsa king Marc, 44, during a visit to Disneyland with his and J.Lo’s 5-year-old twins, Max and Emme. And that enraged the former “American Idol” judge, said the source.

“Jennifer couldn’t stand to see Marc and Chloe kissing and hugging in front of the kids,” revealed the source. “And she practically tore her hair out when she saw Chloe holding the twins.

EVEN WORSE, Jennifer has known Chloe and her father since Chloe was a teenager. She feels totally betrayed, but Marc feels he’s just giving his ex a taste of her own medicine.”

J.Lo and Marc split in July 2011 after seven years of marriage, and she started dating Casper four months later. Marc filed for divorce in April 2012, but it’s yet to be finalized.

“Jennifer and Marc have always been competitive about who’s led a better life since their breakup,” said the source. “Now with Chloe, Marc is feeling smug.”
