Simon Cowell: I would work with Tulisa again
Simon Cowell has revealed he would not "rule out" working with Tulisa Contostavlos again.
It comes a week after the former X Factor judge was found guilty of assaulting a celebrity blogger; days earlier in a separate trial she was cleared of drugs charges.
However, Simon Cowell said he could see himself teaming up with the star.
"She's had a rough time," he admitted. "But she's come through the other side."
Amongst the hundreds of thousands of people who have auditioned for this year's show was the sister of Twilight star Robert Pattinson.
Lizzie Pattinson seemed to choose to keep her famous sibling's identity a secret, with the X Factor boss insisting, "she never told us who she was".
Speaking at the X Factor auditions at Wembley, the 54-year-old also revealed he is planning to "one day" stage World's Got Talent, where international acts would go head to head.
He said: "It's kind of logical that we should do a larger competition world wide with the show."
Cheryl Ann Fernandez-Versini is also returning to the judging panel, weeks after marrying for a second time.
The Geordie singer says this year's panel is the "best" and is particularly getting on well with fellow judge Mel B.
"I said to Mel I thought it would be interesting if we did a Spice Girls versus Girls Aloud theme at some point during the show. It could be fun," she said.
Cheryl thinks ITV will need to use the bleep button during the live shows to cover up Mel's swearing.
"I have to say that she makes me die laughing," the star said. "She's hysterical, I love working with her."
Mel B though claims her swearing on the show has been blown out of proportion.
She said: "I only swore once without the audience when the cameras cut, so I don't really swear that much."
The shows longest running judge Louis Walsh believes the tenth instalment is going to be the "biggest series yet".
He insisted: "It's not the old X Factor, it's the new X Factor."
