After getting a peek at Jennifer Lopez in a pair of skintight white pants, it's pretty safe to say that age is nothing but a number. Well, for some lucky souls!

On Monday afternoon the 46-year-old actress headed to the dance studio to prep for her Las Vegas Planet Hollywood residency, and from her flawless skin to those sexy heels, she looked amazing. So when does J. Lo move to Sin City and what can we expect from her set?

The star's gig starts at Planet Hollywood on January 20, 2016, and she recently told ET Online, "I think I've been preparing for this my whole life. I'm excited about going to Vegas [and] doing the kind of quintessential show that I've always had in my mind. It's gonna have everything that I've been known to do over the years, and it's gonna be a beautiful, glamorous kind of Vegas show. Something that I think people, whether you're a fan of my music or not, would come and see and really enjoy. That's my goal."

We can't wait!
