Young Dumb & Broke Khalid Download 'Young Dumb & Broke' on iTunes
Harry, Niall, Liam, Zayn and Louis say they need a ginger sixth member of the band and they have their sights set on 'The A Team' singer Ed Sheeran.
Ed helped write the boys' first album - due for release next month - and One Direction admit they have a bit of a boy crush on the star.
"Getting to write and record with Ed on our album was an honour. We need a ginger guy in the group. The closest thing we have is an Irish guy, me," said Niall.
Louis Tomlinson also told the Daily Star: "Ed is phenomenal. He's been one of the artists who has blown up in a major way."
The new album also features collaborations with Tom Fletcher from McFly, Kelly Clarkson and Lady GaGa's producer RedOne.
