A night after sharing the stage with her soon-to-be ex-husband, Jennifer Lopez was on the other side of the spotlight with her current main man, Casper Smart.

Enjoying her night off after the Q'Viva! The Chosen Las Vegas concert with Marc Anthony, Lopez, 42, took in a late performance of Cirque du Soleil's Mystre Sunday at the Treasure Island Hotel. A group of friends joined the couple of six months, who sipped on water and soft drinks during the performance. Their snacks of choice? Popcorn and candy.

And she was every bit the golden girl: Lopez stunned in a short, gold-beaded dress with matching gold fingernails and a gold clutch. She topped off her ensemble with diamond star-shaped earrings and diamond bracelets.

It was the ending of a whirlwind Sin City weekend for Lopez, who also launched her new single "Goin' In" with a performance at the Bellagio's Hyde hotspot Saturday.
