Lopez finally enjoyed a night off after the Q’Viva! The Chosen Live concert at Mandalay Bay with ex-husband Marc Anthony, and launching her new single “Goin’ In” with a late night performance at Hyde Bellagio, taking some time for herself, Casper and a group of friends to sit back and be entertained for the first time in a busy weekend.

Lopez did not take a night off from looking amazing however, arriving in a short, gold beaded dress with matching gold fingernails, gold clutch, diamond star-shaped earrings and diamond bracelets. Lopez, Casper and the group sipped on water and soft drinks, and snacked on popcorn and candy during the performance.
