"Resting after Barney's Gaga Workshop opening in NY," reads the caption beneath the pic, in which Gaga (real name: Stefanie Germanotta) curls up in an armchair without a stitch of clothing on save for a flesh-colored thong.
(The Grammy winner seems to have posed for the shot late last year, when her Barney's Workshop opened up as a pop-up store in NYC for the holiday season.)
But Gaga (currently traveling the world for her concert tour) has more than just her svelte bod to show off: She just landed her very first film role as La Chameleon in director Robert Rodriguez's new film Machete Kills.
"Yes its true, I will be making my debut as an actress ln the amazing MACHETE KILLS BY @RODRIGUEZ IM (sic) SO EXCITED!!! AH! Filming was insane," the star tweeted.
