All the smiling, nodding, waving, eye dabbing and dancer action has finally take its toll on the Cole (apologies). As usual, "exhaustion" is the culprit. I would've chosen a different word beginning with 'e', like emaciation, but the term exhaustion is more broad.

By all accounts, the 27-year-old collapsed at a photo shoot. She's since pulled out of The X-Factor on medical advice after passing out in a sweating heap during the shoot for her new album, The Sun reported. A doctor rushed to the North London studio on Saturday and diagnosed "severe exhaustion and a gastroenteritis bug". Sources said the star turned up for the shoot looking "washed-out" and "gaunt."

Make-up artists spent an hour working on her, but after just minutes under the lights she collapsed. But worried friends say Cheryl has already ignored calls to cut back on her 18-hour working days. One friend told The Sun: "She should never have gone to the studio. She insisted she was fine, even though she clearly wasn't. Her skin was pale and her lips had no colour. She's rundown and tired. That's why she ended up with the stomach virus. She told the photographer she'd be all right if she got her make-up on. But once she was under the lights it was clear she wasn't well. She was really sweating and the make-up staff had a job on their hands. Eventually she just keeled over. It was horrible. She was only out for a few seconds but it was enough to give everyone, including Cheryl, a massive scare. 'She was carried to a dark room and lay down on a sofa until the doctor arrived. She was sent home to rest and the shoot was postponed indefinitely. 'It was a real shock to see her looking so ill. She looks terrible."

Cole will be absent from filming The X Factor until further notice following the doctor's orders for complete bed rest. And hopefully some food. It is not yet known who, or if anyone, will be replacing her on the talent show's judging panel.
