Lopez was a vision on the T-Mobile Arena stage in a black leotard, fishnets, thigh high boots, and a zippered sweatshirt.

The Jenny From The Block singer posted a sultry selfie on Instagram after the show that included performances by Ricky Martin and Bad Bunny.

Her hair was mussed up as she pouted her glossy lips and showed off her long lashes and perfectly shaped brows.

The word ‘loopy’ could be spotted on her phone case, which most likely hints to the lateness of the hour in the city that never sleeps.
