The triple-threat is currently dating dancer Casper Smart, who is 18 years her junior! She's described her boyfriend of two-and-a-half-years as "really fantastic" with twins Emme and Max, and ex-hubby Marc Anthony has even given his stamp of approval! But Casper isn't the first younger man J. Lo's fancied. Her first husband, Ojani Noa, is 5 years younger than the singer.
