Britain's Got Talent runner-up Susan Boyle had not ate or slept for one week in the run-up to the weekend finale, according to BGT judge Piers Morgan.
Morgan said Monday On Good Morning America that the 48-year-old singer was 'in a state' prior to being admitted to The Priory Clinic in London where she is being treated for exhaustion.
Boyle - who was runner-up to dance group Diversity on Saturday's finale of Britain's Got Talent - was taken to the clinic by ambulance from The Crown Plaza Hotel in Westminster, London late Saturday.
The Scottish songbird - who has become an Internet global star in less than a month - reportedly ran down the corridors of the TV studio after the finale yelling: "I hate this show!"
When she returned to her hotel she started acting oddly and her assistants called a private doctor to examine her inside her hotel room.
The doctor decided that she was suffering from exhaustion and an ambulance ,followed by police, took her to The Priory Clinic.
Morgan said reports she had been sent to some sort of rehab facility were "massive exaggeration," and that Boyle has no issues with drug or alcohol abuse.
A hotel insider said: "The hotel staff were all concerned about Susan Boyle. Something wasn't right. She looked lost - not at all there."
A spokesman from Scotland Yard confirmed that they had escorted the singer to hospital after she suffered 'an emotional breakdown.'
The statement read: "We were called at 6pm to a central London Hotel where doctors were assessing a woman under the Mental Health Act. She
was taken to a clinic voluntarily at the request of her doctor and police were asked to accompany them. It is not unusual for doctors to ask police to attend in circumstances where they are assessing someone - or to accompany someone to a clinic in cases where this attendance might prove necessary."
Despite coming in runner-up in the finale, Boyle is being tipped to make a fortune with lucrative music and film deals already being lined-up for her.
She has reportedly inked a deal with American Idol's Simon Cowell who will try and guide her career after she became a huge star on the Internet with over 300 million hits on You Tube.
Despite a back-lash from the public before Saturday night's finale over 19.2 million people tuned in to watch her performance, making it the most watched show in the country in the last five years.
