The 'Bad Romance' singer was spotted leaving her hotel in Berlin, Germany on Thursday afternoon (24 October) with an attention-grabbing giant furry creation covering her entire head.
Nope, we're not sure how to describe it either. It's also been suggested by one Reveal worker that the headpiece is like an upside down Cornish Pasty...
Gaga's hat (hairpiece? mask?) appeared to be made of teddy bear-esque material and featured a pair of eyehole cut-outs and what looks like a giant metallic spoon-shaped decoration down the middle.
Kudos to Gaga for keeping her head held high as that thing looks like it could weigh a tonne!
Gaga teamed her odd headgear with a smart mustard yellow trenchcoat belted at the waist. It featured furry arms.
Not having to worry about make-up? Thumbs up! But practical if you're getting on a bus or the tube? Fun for the person behind you in the cinema? Maybe not…
Gaga's on a promotional blitz for her brand new album ARTPOP, which has already spawned the tracks 'Applause' and 'Do What U Want', featuring R. Kelly, and is released 11 November.
She's due to perform brand new track 'Venus' on this weekend's X Factor results show - we can't wait to see what she wears on stage!
