One Direction - BRIT Awards 2013

Brit-winning stars One Direction have revealed that the film crew for their new movie follow them everywhere - even to the loo.

The boy band - Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson - were continuing filming of the documentary as they collected their global success award at London's O2 Arena last night.

They are in the midst of making a 3D movie with the director of Supersize Me, Morgan Spurlock.

Horan - speaking backstage at the awards - said: "Spurlock's here himself. We're shooting the movie now... it's actually just been in the toilet with us - no lie.

"It's going to be very access all areas."

He added: "It's been a good start to the week, because on Saturday we open up our world tour here at the O2, and that's going on until November."

He said the film was due to appear in August. "It's going to be a very exciting year," he added

"It's actually just been in the toilet with us."

He added: "It's going to be very access all areas."

Bandmate Liam Payne chipped in: "Especially in the toilet."

And Niall, 19, joked: "That's something to look forward to."

1D won the Global Success Award and were quick to thank their fans for the success.

Speaking backstage, Niall said: "Our fans are the as amazing all around the world."

Louis Tomlinson reflected: "Its been a great night and it was great performing but to win an award is huge."

Their charity single is number one in 63 countries, Zayn Malik said: "We're just massively grateful to be a part of it and have the opportunity to do something so amazing for such a good cause."
