Cheryl Cole 'Collapses From Exhaustion'
Chez has been forced to cancel all work commitments for the next week...
The Girls Aloud singer, who has just turned 27, fainted a studio in North London on Saturday where a doctor diagnosed her with 'severe exhaustion' and ordered her to rest completely.
Chezza's manager told X Factor bosses last night that the Ashley Cole.
Chezza's pal added: ""Since splitting with Ashley, Cheryl has been throwing herself into work. She has been completely dedicated to X Factor, her album, recording sessions and touring - to an extent that it has started to affect her health."
"Cheryl has been putting on a brave face, joking about hangovers. The truth is, she's simply working far too hard."
The friend explained: "There's only so long someone can do 18 hours every day without burning out. She has worked relentlessly for the past 18 months. Something had to give."
Cheryl's people, Supersonic PR have since issued a statement on Twitter claiming: "Following doctor's advice Cheryl Cole will be cancelling all work commitments for the next week. No further comment."
The exhausted singer is now expected to take a minimum of a week's rest before gradually returning to work.
