Miley Cyrus' little sister was almost unrecognizable at Kylie Jenner's birthday party.

And if you have any thoughts on her new look, well, Noah doesn't want to hear it. "We literally dont care one bit (: isnt that right ken?” she captioned one of her Instagram photos from Jenner's party on Sunday night.
