It looks like One Direction have been whipping up a storm in the US this week.

They boys flew across the pond to film their appearance on iCarly, and were greeted by a crowd of screaming fans outside of the Nickelodeon studios yesterday.

Apparently fans began queuing outside a good 12 hours before 1D even arrived - can you blame them?!

Check out the chaos for yourself in this video!

After filming their appearance on iCarly, the boys have just confirmed they have just touched down on English soil.

Liam Payne tweeted: “Woohooo we are home :) xxx," while Harry Styles wrote: "Touch down!!! Back home :)."

Louis Tomlinson took to Twitter, writing: "Home sweet home :)x"

Home sweet home INDEED.

We're not surprised One Direction are causing chaos in America, are you? Excited they're back in England?
