So in love! Jennifer Lopez paid tribute to her boyfriend Alex Rodriguez when she wore a gold-studded New York Yankees flat bill hat for her Calibash Las Vegas performance on Saturday

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

With long flowing tresses and sun-kissed makeup, JLo looked age defying for her second performance of the traveling Urban Music Festival.

The first show recently took place on January 20 in Los Angeles at the Staples Center where she did a music mash-up of Cardi B’s hit Bodak Yellow.

‘This is a Bronx girl dream. I just can’t believe I.T. The mother @jlo,’ Cardi, who also performed in LA, posted on Instagram.

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.
