She’s “On the Floor” — and in the buff.

Jennifer Lopez posed nude in the campaign for her new JLo Jennifer Lopez for Revolve shoe collection, using her super-long hair extensions to shield her bare body.

The superstar, 53, shared the sexy snaps on Instagram Monday, which highlight a pair of as-yet-unreleased lace-up stiletto sandals from her footwear line.

“Starting the week right,” Lopez captioned the shots, in part — and it would seem her fans agreed.

“These new J Lo visuals are giving us LIIIIIFEEEEE!!!” one fan commented.

“The hair living for it,” another added.

“I think you’ve aged the best outta anybody on this planet…. Seriously,” wrote a third.

Lopez isn’t shy about baring it all on social media.

Earlier this month, the “Selena” star wore only a towel and a delicate gold necklace bearing husband Ben Affleck’s first name for an Instagram video plugging her skincare line.

Her 16-piece shoe collection offers plenty of towering heels and crystal and mesh booties that reflect the ever-glamorous star’s aesthetic.

Lopez told Footwear News, “It’s different from other collections because Revolve is more fashion forward,” describing it as “more of what I like to call the JLO aesthetic: glam, sexy and powerful but at the same time classic.”

The focus of her latest Revolve photo shoot was all on the shoes — unlike the “Shotgun Wedding” star’s ab-baring, high-slit metallic gown at the line’s launch party over the weekend.

Noted one fan of the skin-baring ensemble, “This look does not draw attention to the shoes.”

As for whether her risqué campaign shots accomplish that mission? You be the judge.
