THE stress of the past month is taking its toll on Madonna.
The Queen Of Pop has sacked two dancers and her tour manager is threatening to walk out over her spectacular moods.
And for the first time, despite her incredible fitness regime, her health has started to suffer.
Doctors discovered Madge is anaemic, a surefire sign she is overdoing it, and she also suffered a painful knee injury.
Madge has had a doctor, physiotherapist and a chiropractor on duty during rehearsals for her forthcoming Sticky & Sweet world tour.
This week medical experts ordered her to take her foot off the pedal on the punishing dance routines because her body simply cannot cope.
She is now taking time out and resting in New York state's Hamptons resort with close pal Gwyneth Paltrow.
Madge's meltdown follows some testing times in her personal life.
She has faced claims of a crisis in her marriage toGUY RITCHIE and allegations that she is a home-wrecker over her relationship with baseball starALEX 'A-rod' RODRIGUEZ.
And a book penned by her brother Christopher Ciccone has lifted the lid on family secrets and tensions. The strain has pushed her famous mood swings to terrifying new extremes.
A source in her camp said: "Madonna is doing less than OK. She has been rehearsing for the tour and she is totally miserable.
"She's down physically and mentally. The situation with Guy is very, very tense. The way the press are going crazy with the A-rod story, her brother's book and her physical exhaustion are all taking their toll. "Family tension with her father and two of her other siblings has also been awkward.
"She feels nobody has taken her side. One of her closest pals says she has never seen Madonna so low. She has been feeling low and looking really gaunt.
"Madonna was told to go soft on work and rehearsals, so she will now take one proper day off every week and go easy in the mornings.
"She has a blood analysis done every few days - including one during last Friday's rehearsal in front of everyone."
I reckon it may be a good time for Guy to take up golf.
