Jennifer Lopez Low-Cut Dress and Casper Smart Pictures at 2012 Vanity Fair Oscars Party

Jennifer Lopez swapped one revealing dress for another as she moved from the Oscars to the Vanity Fair party at Sunset Tower yesterday. For the show, Jennifer wore a Zuhair Murad gown, with a similarly deep V-neckline as this sequinned number. J Lo faced possible nip slip controversy when she presented alongside Cameron Diaz at the Academy Awards, but Jennifer's stylist asserted that double-sided tape kept everything in order on stage. While Jennifer didn't bring her boyfriend Casper Smart onto the red carpet, the twosome did hook up for the exclusive VF bash.
