McFly bassist Dougie Poynter has described a track the band co-wrote with One Direction's Niall Horan as a ''stadium epic''.
Poynter, 25, hopes the song will be chosen to appear on the next One Direction album although no release date for the project has been set.
"It hasn't got a title at the moment but we wrote the song with Niall," he said.
"He's got some good ideas so had a lot of input."
It's not the first time McFly and the 2010 X Factor finalists have worked together.
The tracks, I Would and Irresistible, from One Direction's 2012 album Take Me Home were written by McFly lead singer Tom Fletcher.
"They are smart guys. They know what they're doing. They play to arenas and stadiums around the world," added Dougie.
"So I think it's a bit of a challenge to come up with some songs to go with that."
Waiting to record
Dougie Poynter was crowned winner of the 11th series of I'm A Celebrity Get Me Out Of Here! in 2011.
McFly's last studio album, Above The Noise, was released in 2010. Dougie revealed they are ready to get back in the studio.
"We've written all the songs we are just waiting to record them," he said.
"Tom (Fletcher) is one of the best songwriters around but we have all had an input.
"We have this great sense of freedom. When you're younger you write a song then ask yourself, 'Is this cool?'.
"Now we are just like, 'Look, we are very good at writing pop songs'. So, I think what comes out next will be very pop but still very guitar driven."
