One Direction: iCarly Guest Stars!

One Direction pick up their steps as they rush to catch their flight at Heathrow Airport in London on Friday afternoon (January 27).

The guys — Louis Tomlinson, Niall Horan, Harry Styles, Liam Payne and Zayn Malik — will be guest starring on iCarly!

According to MTV News, “The guys will be on set Monday to tape their appearance on the episode, during which they will play themselves and perform ‘What Makes You Beautiful.’”

In the episode, Carly (Miranda Cosgrove) returns home sick after a trip and discovers that One Direction has accepted an invitation to perform on their web show. Not long after arriving, bandmate Harry becomes sick and we see Carly doting over him.
