One Direction To Guest Star On new iCarly Episode

is about to feel the effects of a British Invasion. The show has just booked British boy band One Direction to appear on the fifth season of the Miranda Cosgrove-starring show.

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."

According to a synopsis of the episode, "Carly 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. Realizing Harry is playing sick for the attention, they hatch a plan to get him back in the group by telling him Gibby has become their newest bandmember. Meanwhile, Spencer becomes a personal trainer and gives a bratty girl a makeover."
