Cheryl Cole is said to be depressed following her alleged exit from The X Factor USA last week.
Cole is widely reported to have been axed from the judging panel of Simon Cowell's new show and friends of the singer say she has not stopped crying since returning from America.
"Cheryl wasn't in the right frame of mind to commit to such a big project like The X Factor USA and it has ended up making her feel even worse after being rejected," a source close to Cole told The Mirror . "She felt lost and just didn't enjoy life in America."
The insider claimed that Cole's problems became apparent as soon as she arrived in the US to begin work on the show.
"She was telling people she wanted to go home and although she was smiling for the cameras she was crying inside," they continued. "She spent weeks feeling homesick and staying in her hotel room."
Cole is said to have flown home from the US last week to stay with her family, and has so far kept a low profile.
"She is taking hardly any calls and there have been lots of tears all week, she is really down and depressed," the source added.
Cole, Cowell, and ITV1 have yet to make any comment regarding the singer's current status with either the US or UK versions of The X Factor .
Yesterday, N-Dubz star TulisaContostavlos was officially confirmed as one of the new judges for The X Factor UK, alongside Gary Barlow and returning judge Louis Walsh.
Former Destiny's Child member Kelly Rowland is widely expected to be announced as the fourth and final member of the show's judging lineup.
The X Factor UK is scheduled to begin auditions in Birmingham this Wednesday.
