Jennifer Lopez, 43, is never a single lady for long! She's had high-profile relationships with celebs such as Sean "Diddy" Combs, Ben Affleck, Bradley Cooper, and the husband she split with in July 2011, Marc Anthony. When she moved on to a new guy last November, the lucky man was 18 years her junior! Dancer Casper Smart, who's now the choreographer of J.Lo's current world tour with Enrique Iglesias, is just 24. Still, Lopez insisted recently in an interview with Katie Couric that it's not something she and her boy toy spend a lot of time discussing. "Until somebody brings it up, I don't think we really think about it. We're just two people who have similar interests and love a lot of the same things and who get along."
