Madonna Shows Off Her Exposed Chest in Raunchy Throwback Photo for Jean Paul Gaultier's Birthday

Madonna isn't Madonna without a little risquè moment every once in a while — or all the time!

On Tuesday, April 25, the Queen of Pop took to Instagram to wish her good friend Jean Paul Gaultier a happy birthday, and decided to share some blasts from the past in the process.

"Happy Birthday JPG!" Madonna wrote alongside a stunning black and white throwback shot of the duo softly smiling side by side.

The "Material Girl" signer proceeded to upload a series of other snaps of the pair from years ago on her Instagram Story. One photo portrayed a young Madonna lounging across Gaultier's lap as he pretended to lift his arm in the air in the motion of slapping her behind.

Another image featured the the French fashion designer kissing the pop star's cheek as she chowed down on a piece of strawberry shortcake.

Madonna then shared a picture from her infamous 1992 runway moment, when she shocked the crowd by wearing a striped form-fitting dress that revealed her chest at an amfAR fashion show, while Gaultier proudly stood by her side to show of his alluring design.
