Although it seems like only yesterday that One Direction hit the "X Factor USA" stage (in fact, it was a few weeks ago), the British boy band returned for the season finale to perform their latest single, "Kiss You." Watch in the video above. Highlights of the event included: A retro video game throwback, awkward dancing on top of giant plastic lips, matching white shoes, and a whole lot of visible tattoos.
Considering 1D are arguably the franchise's biggest success story -- despite the fact that they were eliminated before the finals -- it seems fitting that they would have such a heavy presence on both the American and U.K. versions of the show this season. And, honestly, we can't think of another boy band on the planet who would have been more welcome for a second showing.
Do you think they've come a long way since their 2010 "X Factor U.K." auditions? Sound off in the comments below or tweet us your thoughts @huffpostteen! (We've included a brief video history of their careers in the slideshow below, for reference.)
