Marc Anthony — A Male Cougar

It must run in J-Lo’s family.

Not only is Jennifer Lopez dating someone 18 years younger (Casper Smart) — so is her ex husband, Marc Anth0ny.

In fact, he’s got her beat, the Latin crooner is dating an heiress, who is 22 years his junior.

The 44-year-old, who is back with 22-year-old Chloe Green after a split a few months ago, is spending a romantic getaway in St. Tropez on daddy’s $48 million yacht.
