LADY GAGA has once and for all proved that she is completely off her rocker with two wild outfit choices.

CRAZY: Lady Gaga’s wild outfit choices [SPLASH]

The wacky songbird was spotted today leaving her London hotel to head to Captial’s Jingle Bell Ball – in what looks like her craziest get-up to date.

Although the star has never been afraid of flashing the flesh, she gave a whole new meaning to scantily clad as she wore see-through knickers on top of her racy fishnet tights.

Completely ignoring the bitter winter temperatures, The Applause singer bared her midriff as she stepped out in an open jacket and lacy orange bra.

If it’s possible to maintain while dressed as a crazy wizard from the 1970s, Lady Gaga covered her modesty with sparkly star-shaped nipple pasties.

Mother Monster teamed her underwear and patterned jacket with some crotchless chaps, completing her look with mis-matched platform boots and glasses with heft jewels instead of regular lenses.

Never a one just to nip out in jeans and a hoodie, last night Lady G wore an elaborate leather dress and enormous black headdress for a night out in London.

The skin-tight dress encased the tattooed star’s curves in a mesh like pattern, with leather tassles swaying as she walked.

The wacky songbird wrapped her bleach-blonde weave around the doughnut style hair accessory, pulling it into a tight ponytail at the back.

The singer also donned some kinky knee-high boots to complete her S&M look, keeping her pale pins bare and exposed.

Whatever will she wear to top these exaggerated ensembles?!
