Since they go their start on "X Factor UK" almost three years ago, the boys of One Direction have had a number-one album, number-one singles, world tours, and every bit of fan merchandise imaginable created in their honor. Last week, the superstar boy band went back to where they started, performing their new single "Kiss You" on the finale of this season's "X Factor UK." Although Perez Hilton criticized the performance as "less than stellar," fans seemed to be on board with the high-energy new single.

It's been a busy few weeks for the 1D boys: In addition to performing on "X Factor," they've also had a whirlwind trip to New York that included two big performances at Madison Square garden -- one for their headlining show and one at the Z100 Jingle Ball.

Were you into their performance? Do you think "Kiss You" will be as big as "Live While We're Young"? Tell us in the comments below or tweet @HuffPostTeen!
