The 'Do What U Want' singer was spotted heading to her London hotel in the early hours of the morning sporting the rather eye-catching ensemble.
In true Gaga fashion she stunned us all with her outlandish style choice, wearing a peculiar red playsuit with tiered shorts and a ginormous neckline.
But it was her head gear which really had us gawping. It looked like the starlet had snipped a chunk from her Christmas tree before fashioning it into a rather strange headpiece!
She decorated her seasonal accessory with red, blue, purple and gold baubles before topping with a sparkly red star.
To complete her extravagant look, Gaga rocked bright green hair and fishnet tights, plus her favourite platform patent boots. Gulp.
Before changing into her festive off-duty look, the songstress sported an equally unique get-up as she took to the stage to headline Capital FM's Jingle Bell Ball.
She kept her eye-popping boots the same but opted for a matching trouser and jacket combo adorned with a starfish print.
The 'Applause' singer left her black lace bra on full view while piling up the bling with a rather heavy looking gold necklace.
To finish? Red lipstick and the longest dreadlocks we've ever set eyes on.
And as if two crazy outfits weren't enough, Gaga flaunted yet another odd look earlier that day as she made her way to the Ball.
Leaving very, very little to the imagination, the singer wore a see-through balconette bra and some super-raunchy mesh knickers.
Seriously Gaga, put it away!
