5) Bruno Mars
If you're a Mars fan, you've likely seen him perform 'Treasure' at least once, if not a million times, but have you ever seen him do it with a punk rock flare and an intro jacked from 'It Takes Two'? No. Because keeping things fresh is what being an entertainer is all about!
4) Disclosure, Lorde and AlunaGeorge
What do you get when you blend 'Royals' and 'White Noise'? A seriously club-ready anthem that'll have you off your feet and dancing in no time.
3) Ellie Goulding
From the acoustic-y version of 'I Need Your Love' to the pyro-filled 'Burn', Ellie's medley was defs a hit. Not to mention her tiny outfit also passed with flying colours and was instantly the talk of the town. Personally, we really loved her drum solo a la Imagine Dragons.
2) Katy Perry
When KP puts on a show, she REALLY puts on a show and last night was no exception. Trading in her recent Geisha outfit for an Egyptian look and set - in neon, of course - Katy rocked it with an explosive rendition of 'Dark Horse'. The dance moves could've been better, but we'll just pretend they never happened.
Queen Bey chose the BRITs as the perfect setting for her first ever live performance of love song 'XO' and kicked things off by melting our hearts, saying, "I'd like to dedicate this song to my incredible fans — I love y'all." Awww! Catch a little taste below...
