And while it was Lily Allen's hair we lusted after, and Georgia May Jagger's nails we drooled over, it was Gaga who won our award for best eye make-up of the evening.
Who'd have thought it?!
Gaga stunned on the red carpet in a scarlet red, sequinned Tom Ford dress complete with fishnet detailing around the neckline and matching fishnet gloves. She was also dripping in beautiful Bvlgari jewels and wore some killer Brian Atwood platforms (below).
But while her outfit was nothing short of dazzling, her hair and make-up took a much more demure approach.
The Poker Face singer's hair was pulled back into a clean updo and she wore barely-there lips, matte skin and just a touch of eyeliner and nude shadow.
But then came the piece de resistance – eye jewels!
Gaga has been making bejewelled eyes a bit of a thing this year – she rocked some sparkly eye furniture back in June when she covered her eyebrows in gold gemstones.
And now she's taken them a little further south by lining her top lashes with jewels.
Now that's a look we can get on board with. Meat dresses and rubber gloves, not so much. But diamanté eye make-up? Yes, absolutely.
If you fancy copying her look – and it's the party season, so obviously you do – we've found the perfect cheat's way to do just that. How so? With Stargazer Diamond Eye Liner, £4 for a pair, stargazer-products.co.uk which you just stick above your top lashes and go.
