Pop icon Jennifer Lopez spent her Saturday night performing at the iHeartRadio Music Festival at the MGM Grand and then headed over to Chateau Nightclub & Rooftop at Paris Las Vegas, where she celebrated her upcoming residency at Planet Hollywood’s Axis Theater.

Fans who waited for JLo’s arrival on the red carpet weren’t disappointed when she appeared, wearing a white Michael Costello suit with a deep neckline.

Her hit song, “All I Have,” played as the pop star walked into the nightclub. She sat at a VIP booth in the center of the main room, and the nightclub’s cocktail servers presented her with a customized, engraved bottle of Yellow Label Vueve Clicquot.
