On July 18, Lady Gaga Instagrammed a photo of her aboard her private jet, captioned: "FASHUN: Vintage Mugler on the plane Listening to Miles Davis My favorite is Flamenco Sketches." Cute, Gaga! But, um, can we possibly touch on the fact that your right boob is completely hanging out of that vintage Mugler? Because your right boob is completely hanging out of that vintage Mugler.
I'm gonna go ahead and guess that the "G.U.Y." singer's NSFW nip-slip photo -- which we've blurred below -- was unintentional, but I'm sure that Rumer Willis, Rihanna, and Cara Delevingne would welcome her with open arms at the "Free The Nipple" lunch table in case it wasn't.
UPDATE: Lady Gaga has since deleted the photo from her Instagram account and tweeted, "Where is the face palm emoji when u need it."
