Cheryl Cole not returning to USA X Factor?

Cheryl Cole will not return to The X Factor USA, according to a report.
The 'Promise This' star's position on the show has been in doubt since it was claimed that she had been axed from the Fox series two weeks ago. However, over the weekend it was reported that Cole had been offered a return.
Various tabloid reports suggested that the offer was made for the 27-year-old to join Simon Cowell, Paula Abdul and Antonio 'L.A.' Reid in New York on Wednesday to film auditions. 
The Hollywood Reporter has now claimed that Cole won't return to the show after bosses decided to let her go. She is expected to be paid the $1.5 million she is owed, after she apparently signed a "pay or play" contract.
"There was no spark," a source said of Cole and her fellow judges. "It was nobody's fault. It just didn't work." 
The X Factor USA axing allegedly left the Girls Aloud star 'extremely upset', causing communication between her management and producers to break down.
Production firm FremantleMedia is said to have offered Cole her job again, while hoping that she would not turn up to auditions - at the same time preventing the company from having to pay her.
However, the former X Factor UK judge has compiled evidence to prove that she was initially sacked, The Mirror claims.
"They're hoping it's a no-show so they don't have to pay her. But that plan falls flat when you look at the fact of the matter – that she's already been fired," a friend told the paper. "There was a meeting attended by Cheryl where it was made clear it wasn't working. Then there are emails and messages to the same effect.
"For the network to try and wriggle out of it by suggesting otherwise is nonsense. If she doesn't turn up to retake her place on the panel, she is not in breach of her contract - because Fox breached it themselves."
Other UK media reports claim that Cole is still deciding if she will accept the offer to return, with one source concluding: "At last Cheryl is in charge of the situation. She's finally calling the shots, but she's really not sure."
