X Factor host Dermot O'Leary says the show's judges are yet to be confirmed.

There has been much speculation surrounding the state of the panel since the end of last year's show which featured Gary Barlow, Nicole Scherzinger, Tulisa and Louis Walsh.

Rumours that Sharon Osbourne and Robbie Williams names have featured in the possible list of big names, but O'Leary says he is being kept in the dark.

In an interview with ITV he admitted: "No one has been confirmed."

The star also spoke about his burgeoning friendship with Barlow.

He said: "I get a few texts from Gary from time to time [and] we see each other quite a lot and he's the one I go out for dinner with and have fun with."

Olly Murs recently announced his departure from his hosting duties on The Xtra Factor. O'Leary says the star will be missed, adding: "Well I will miss Olly because he's like a little brother to me, but I'm so glad for him, because he loves doing this and the only reason he wouldn't do this is because he's so busy."

Reports have suggested last year's contestant Rylan Clark will replace Murs on the show, alongside Caroline Flack.

O'Leary added: "I think Rylan would be good but the most important thing is that Caroline is happy."
