Billboard Music Awards 2013: Jennifer Lopez boyfriend Casper Smart mistaken for ex-husband Marc Anthony

marc-anthony-casper-smart-billboard-music-awards-2013-gi.jpg Jennifer Lopez got photographers so hot and bothered when she stepped onto the 2013 Billboard Music Awards blue carpet, that they momentarily lost their minds and mistook the 43-year-old "Live It Up" singer's 25-year-old boy toy, Casper Smart, for her ex-husband, 44-year-old Marc Anthony.

J.Lo kept up the "skin is in" fashion trend, wearing a sheer-bottomed gown she seemed to be precariously taped into, thanks to a plunging neckline.

Casper wore a black suit, which he paired with brown shoes, no necktie, and a pair of shades that went one step beyond making him look famous, and actually disguised his identity. Of course, it's possible the photo agency just had a memory lapse and forgot J.Lo and Marc had split.
