Leave it to Jennifer Lopez to always look hot — literally.

The pop star, 49, was seen out and about in New Jersey on Friday dressed in head-to-toe sweats just after a local state of emergency was declared due to blazing temperatures not too far away across the Hudson River in New York City.

However, Lopez who is in the middle of her “It’s My Party” tour, paid no mind to any weather warnings as she sported her Guess camo sweatsuit — with her hood up — ahead of her performance at Newark’s Prudential Center as temperatures topped 90 degrees.

After last weekend’s blackout that shut down her show at Madison Square Garden, Con Ed also warned that with the ongoing extreme heat, more power issues can be expected.

But for someone who glistens instead of sweats, J.Lo was ready for her show regardless.

“Real Housewives of New Jersey” star Melissa Gorga attended the show and posted a photo on Instagram with the iconic singer.

“My girl put on a killer show!” she wrote.

Lopez will perform in Philadelphia on Saturday night.
