Former X Factor star and Celebrity Big Brother winner Rylan Clark has slammed Justin Bieber, calling his delayed London gig 'disgusting'.

The Big Brother star said that Bieber should have been on time, when speaking to Digital Spy at the Loaded Lafta awards.

"I wouldn't ever do that. I can't believe it," Clark said. "I think it's disgusting. Absolutely terrible. I'm not being funny, but I came straight out of the Big Brother house, had 45 minutes' sleep and I was bang on time for my tour the same day - so he could have done the f**king same."

Clark went on to speak about the rumours circulating in regards to new X Factor judges - and said that he supports Sharon Osbourne's possible return.

He said, "I'd love to see Sharon Osbourne back. I think she does a great job and it's time she returned. And any Spice Girl - they're always nice to add to the line up. Geri's my favourite.

"I think she'd do a great job... I know there's a lot of rumours flying about me joining The Xtra Factor, but I don't know whether Olly [Murs] and Caroline [Flack] are doing it.

"Things don't get decided until like the day before. I'm flattered that my name's been brought up, and if the opportunity comes along, then we'll discuss it."

Could Rylan Clark soon be replacing Olly Murs on The Xtra Factor?

However, Clark did say that he has no plans to become an X Factor judge himself. "If I was to, I think that would be the end of X Factor, let's be honest," he admitted. "I think I'm a bit more Britain's Got Talent.

"I'm on this series of Celebrity Juice. I'm not the new Jedward - I'm the new Rylan. Jedward might be making an appearance as well, you'll have to watch."
