The 27-year-old actress, known for her odd attires, had an inverted triangle, which looked like being made from matted blonde hair, balanced on her head with a gold bar placed over her chin and giant fur sleeves resembling an animal draped over her shoulders.

There were even two tiny eyeholes pierced through the mask, but the singer still held onto a man's arm for guidance, the Daily Star reported.

The, Applause hitmaker, who was there to promote her latest album, Artpop, had worn her favourite skyscraper heeled boots with the bizarre outfit.
