One Direction guest starred in what may be the most highly anticipated episode of 'iCarly' ever. In case you missed last night's premiere (for shame!), fear not, Directioners! Clips have hit the Web.

In the ep, Carly (Miranda Cosgrove) hears that One Direction agreed to perform on her web show and is beyond ecstatic. When the guys show up for rehearsals, things are going great. The guys goof around and deal with flirting from just about everyone on set except Carly herself -- including Gibby!

However, Harry Styles gets sick (Carly thinks she gave him "jungle worms") and relishes the extra attention he gets as a result ... and Carly later learns that Styles faked his sickness for attention. As if it were necessary!

Can't wait for a rerun? Tide yourself over by watching the snippet below and check out their promos and on-camera performance of ‘What Makes You Beautiful.’ If you also missed One Direction on 'Saturday Night Live,' you can watch their skit and performances here.
