The absent Adele won awards for 'Favourite Female Artist in Pop/Rock', 'Favourite Album in Pop/Rock', and the coveted 'Favourite Artist in Adult Contemporary'.
But it was Taylor who won the evening's biggest prize, 'Artist of Year'.
On Twitter she wrote: "I had one of the most magical nights with my friends tonight! Hopping on a redeye to play our last 2 shows at Madison Square Garden!!"
David Guetta and Nicki Minaj opened the show with 'Turn Me On' which morphed into Nicki's 'Super Bass'. The show ended with LMFAO performing aural atrocities 'Party Rock Anthem' and 'Sexy And I Know It', during which they were joined on stage by Justin Bieber and Germany's favourite popstar, David Hasselhoff.
