Niall Horan believes he would be "the worst judge ever" on 'The X Factor'.
The One Direction star has been rumoured to be taking a place on the judging panel for the singing competition's upcoming twelfth series, but dismissed the claims by saying he would be "terrible".
Speaking at Capital's Summertime Ball with Vodafone, he told BANG Showbiz: "I'll be the worst judge ever. I'll be terrible."
Bandmate Louis Tomlinson also took the opportunity to refute claims he'll be taking a spot on the panel.
Brushing off rumours, he said: "I've got a tour to do so unfortunately not."
Fellow 'The X Factor' stars Little Mix insisted they are hoping for a surprise comeback for Tulisa Contostavlos, who appeared as a judge for two series' in 2011 and 2012.
Jesy Nelson said: "We are all team Tulisa and Chezza (Cheryl Fernandez-Versini)."
Leigh-Anne Pinnock added: "We are going to miss Louis. He's such a big part of the show so it will be weird seeing him go."
Meanwhile Olly Murs, who has taken over presenting duties along with Caroline Flack from veteran host Dermot O'Leary, teased plenty of changes for the prime-time show, all of which he is "excited" for.
He explained: "I'm excited because the boot camps are changing, judges' houses are changing, the live shows are going to be different. It's going to be something new for everyone.
"We want people who are going to be fun on the panel with big, strong personalities so I'm hoping Simon will get the right team."
