One Direction Appear On The X Factor Results Show
Stars get suited and booted for pre-recorded performance...
The boy band might have been performing live at the American Music Awards across the Atlantic on the same evening, but the miracles of modern technology (aka video recording) made it possible for them to sing on the UK show too.
Wearing a selection of smart suits, the fivesome took to a stage backed by hundreds of small candle-like lightbulbs as they delivered an atmospheric version of their current single Story Of My Life.
Asked by show host Dermot O'Leary about their highlights of the year, Zayn Malik replied: "There have been a lot of highlights, the tour was amazing and to be home and see the UK fans."
But Harry Styles buttered up his hosts by stating simply: "X Factor."
And the boys also impressed US viewers with their live performance at the AMAs, where they collected an award for favourite pop album.
They will need a rest after a busy weekend which also saw them taking part in a seven-hour live streaming marathon for "One Direction Day".
