Jennifer Lopez wears black dress with thigh-high slit to promote new show 'World of Dance'

Hellooo J.Lo!

Jennifer Lopez, 47, proved she just gets hotter with age as she hit the NBC Summer Press Day red carpet for her upcoming show, "World of Dance."

The Latina beauty wore a black Elie Saab wrap dress with gold detailing and a sexy pair of Christian Louboutin heels. Her ensemble flashed a lot of skin -- which we're sure is nothing new for the singer -- with a plunging neckline and super racy thigh-high slit.

The "All I Have" singer also posed with her co-stars, including Jenna Dewan Tatum and Derek Hough. The gang looked like they had major chemistry, so we can't see all their shenanigans when the show premieres later this year.

However, the mother-of-two hit the red carpet without her new beau, former Yankees player Alex Rodriguez.

Their new romance looks anything but casual as they've already hit major milestones after just a few weeks together. Jennifer and Alex went a tropical getaway in the Bahamas just a week ago, where they were spotted packing on the PDA during a boating excursion.

The two have also been hanging out with each other's families. Most recently, Jennifer was spending time with Alex's sister. And judging by the selfie Alex's sister posted with J.Lo, she definitely approves of this relationship!
