Two members of One Direction have dismissed speculation linking them to X Factor judging roles.

The panel for the 2015 series has yet to be revealed and Niall Horan and Louis Tomlinson have been suggested.

However, they stated at the Capital FM Summertime Ball in London on Saturday (June 8) that it's not going to happen.

Tomlinson said: "I've got a tour to do so unfortunately not."

Horan added: "I'll be the worst judge ever. I'll be terrible."

Last year's judging panel featured Simon Cowell, Louis Walsh, Cheryl and Mel B.
