Jennifer Lopez & Casper Smart

Jennifer Lopez and Marc Anthony's marriage may be dunzo, but the two are still spending lots of time together promoting their talent show "Q'Viva!" And they've got a third tagging along -- her 18 years younger backup dancer beau, Casper Smart. The two have been dating for months and Casper has already been seen bonding with her twins with Anthony, Max and Emme. Three's company?
