Robbie Williams wants to perform with Rylan Clark on the 'X Factor' final.

The 'Candy' hitmaker is a big fan of the flamboyant singer and though he thinks Kylie Minogue would be a better performer for the hopeful, he would happily step in if given the chance.

He said: "If Rylan does get to the final then maybe it will be me. I wouldn't mind. I'd love that, I love Rylan. I think Kylie Minogue might do a better job with Rylan because I think she's dancey and poppy but if needs be I'll turn up if they're short.

"[We'd sing] 'Islands In The Stream', which is not very Rylan, but I think 'Islands In The Stream' with me and Rylan would be very entertaining, a disco version."

Robbie's Take That bandmate Gary Barlow is currently head judge on the show, and though the 'Angels' singer has no idea if his pal will return for a third series, he thinks programme chiefs would be "lucky" if he did.

He told the Metro newspaper: "'I know he wanted to come back this year and put his stamp on it and I think he's done that and I think he's done that very well.

"If he comes back, 'The X Factor' will be very lucky to have him, if he doesn't, I'm sure he'll find something to do. Gary's his own man."
