If these past few weeks are anything to go by, it seems that a big TV finale isn't really a finale without One Direction popping up and performing - you've got to hand it to Simon Cowell, he knows how to get us watching.
But while we'd barely recovered from their X Factor UK gig complete with Harry Styles' dangly earring of joy, now the lads have returned to the American equivalent for an incredible rendition of their newest song Midnight Memories. And it was GLORIOUS.
Yep, the boys ditched the smart attire they rocked for their Story of My Life promo and opted for a much edgier look to match the song that pretty much makes us want to stroll up to that lad we've fancied for ages and snog his face off. MIDNIGHT MEMORIES IS DANGEROUS TO OUR HEALTH, OK.
