The 'Applause' singer was certainly not afraid of flashing the flesh as she wore her underwear as outerwear while in New York yesterday (2 April).
Gaga was on her way to appear on the Late Show with David Letterman, and made the odd choice of wearing just her bra and knickers, despite the chilly NY temperatures!
The starlet opted for a fancy bra for the occasion - a black number covered in silver embellishment - paired with plain matching briefs.
She also wore fishnet tights which were pulled right up so they nearly hit her belly button, along with her usual sky-high platform shoes.
Thankfully she did cover up (slightly) with a leather biker jacket, topping her look with a red mani and Ray-Ban sunnies.
And of course it wouldn't be a Gaga outfit without a crazy hairdo, and this time she really outdid herself by showing off a ginormous lime green curly bouffant!
Her hair on its own would have turned more than a few heads, so why the risqué outfit to go with?
We'll never understand!
