Remember When One Direction Appeared on 'iCarly'? - Watch It Now!

We’re taking you back to 2012 with this epic throwback of One Direction on Nickelodeon’s iCarly!

The guys – Harry Styles, Niall Horan, Louis Tomlinson, Liam Payne, and Zayn Malik (yes, before he left) – looked so young in the episode.

In case you don’t remember, Harry got sick when he accidentally drank from Carly’s (Miranda Cosgrove) water bottle.

The group performed their first hit single “What Makes You Beautiful.”

Executive producer Dan Schneider uploaded the video to YouTube.
