Napoleon Dumo and Tabitha Dumo (aka Nappytabs) directed the show.
Lopez's act features a live five-piece band and 16 dancers.
Lopez's looks were esigned by Donatella Versace with help from costumers and stylists Rob Zangardi and Mariel Haenn.
Lopez sang her biggest hits, including "Love Don't Cost a Thing," "Jenny From the Block" and "Get Right."
"If there's anything Jennifer is known for, it's glamour. We decided to go over the top with a belted Swarovski crystal jacket, adorned in luxe white feathers from head to toe," stylist Rob Zangardi told Vogue. "This is the ultimate Old Hollywood 'just lounging look.' And by 'just lounging,' we mean exuding all kinds of exaggerated glamour."
In addition to performing in Sin City, Lopez is also judging Fox's American Idol and starring in NBC's Shades of Blue.
For her first show, Lopez invited three special guests to perform with her: Ja Rule ("I'm Real"), Ne-Yo ("All I Have") and Pitbull ("On the Floor").

After her first show, Lopez said, "We worked really hard on it so people could have a good time, and everybody at the end of that concert was on their feet dancing and jumping and singing."
