Simon Cowell has hinted that Robbie Williams could make a surprise appearance on this weekend's X Factor final.
The judge insisted that it is not too late for the former Take That star to perform on the show, adding that the public are in for a surprise.
"I would love Robbie to be there on Saturday night. And it's never too late," he said. "He's still one of the biggest stars in the world. He's great.
"You might be surprised on Saturday, I wouldnt go along with everything you read!"
Asked whether he thinks Williams should rejoin Take That, Cowell responded: "That's a tricky one, I think I'd keep it as it is. He could do a guest slot now and again."
The X Factor concludes Saturday at 7.10pm and 9.40pm on ITV1.
