To kick off the show, the 42-year-old J-Lo arrived in a ’60s-inspired beaded white halter dress that — yep, you guessed it — showed off her legs.
What else did she do during the show?
Later on, she showed off a whole lot more — including her vocals — when she took to the Idol stage for the first time this season, to perform her hit single, “Dance Again,” surrounded by a bunch of sexy, shirtless men.
As an added bonus, J-Lo — who is currently dating 24-year-old back-up dancer Casper Smart, also posed for a quick photo with her twins Max and Emme, who sat alongside their mom at the famous judges’ table.
Clearly, last night belonged to J-Lo!
