The American Horror Story actress chose this amazing hexagon, chain-mail dress by Tom Ford which boasted an eye-wateringly high side split and matching gloves that snaked up her arms.
But while there's no doubt that the dress was absolutely stunning, Gaga seemed to blend in with the carpet as she made her debut on arrival, allowing guests like X Factor's Cheryl Fernandez-Versini and Victoria Beckham beat her in the style stakes.
Even the Poker Face singer's Brian Atwood sky-scraper stilettos and her boxy leather clutch bag matched the luxe red carpet. In fact, we almost lost her for a second - but we'd rather that over the stench of a meat frock.
Mmhmm. We're still not over it.
That said, the superstar who never really does lacklustre appearances, went all out when it came to her make-up, phew!
Gaga jazzed up her beauty look with a smattering of rhinestone crystals along her lash-line and across her gilded lids - and because we're totally amazing, you can copy the trend with this simple How-To right here.
Once again, the American babe bleached her power brows to match her platinum blonde locks and offset her ensemble with a slick of peach-toned lip gloss and crystal drop earrings a la Rita Ora.
What's next we wonder?
