Who? Lady Gaga.
What? Enjoying a night out with photographer pal Steven Klein at her perfume launch party in New York, wearing a floral face-covering full-length pointy concoction that frankly defies explanation.
Why? Why not? Is perhaps the more pertinent question. Maybe she has a ginormous zit, maybe she's making some kind of political statement for or against the Ku Klux Klan, maybe she melts when exposed to bright lights, or perhaps she simply got trapped in her duvet cover and didn't have time to escape.
