Ahead of her performance, the brunette beauty shared a "#preshowpic" of herself cuddling with Rodriguez in her trailer.

When it was show time, the former MLB pro watched as his girl strutted her stuff on stage in a bedazzled New York Yankees hat, glitzy leotard and sparkly jacket.

She later changed into a long-sleeved black gown, which featured two thigh-high slits and gold embellishments from top to bottom.

"Lola in the City...," Rodriguez captioned an Instagram video of Lopez rocking the chic dress. "#nituniyo #NYC#4thofjulyweekend?????."

Following the performance, the lovebirds were spotted out and about, holding hands and paying no mind to onlookers. Lopez was still donning her gorgeous black gown, while Rodriguez kept it cool in an all-white ensemble and blue suede shoes.
