Watch One Direction on X Factor and a bonus Ellen DeGeneres performance!
Zayn, Louis, Liam, Niall and Harry took to the X Factor stage, which started on a giant pair of lips, for an energetic performance of the hit tune, singing their hearts out for Uncle Simon, who made them what they are today.
The guys (except for Harry) left L.A. last night and headed home for the holidays...we wonder if there will be any Haylor sightings today!
Bonus One Direction performance alert!
The guys performed an extra song on the Ellen DeGeneres Show, which the talk show host shared yesterday as a gift--check out "Little Things" below.
