Internet singing star Susan Boyle has been admitted to a private mental health clinic in London suffering from exhaustion, according to British media reports.
Boyle, a 48-year-old church volunteer, had been hot favourite to win television's popular Britain's Got Talent contest, but could only take second place.
Dance group Diversity beat the Scottish singer to be named the winner and collect Stg100,000 on Saturday night in a final watched by an audience of 18 million.
Nearly 4 million people phoned in to choose a winner, with Diversity taking 24.9% of the vote ahead of Boyle's 20.2%.
Police said a woman was taken voluntarily by ambulance to a clinic. Officers were called to a London hotel on Sunday at 6pm local time to doctors assessing a woman under the Mental Health Act.
The Sun reported that Boyle was admitted to The Priory Clinic suffering from exhaustion and that a spokesperson for Britain's Got Talent said she was exhausted and emotionally drained.
The North London clinic said it could "neither confirm nor deny the reports."
On Sunday, it emerged Boyle was taking time off on the advice of a doctor.
Meteoric rise to fame
Boyle became an international singing sensation after first performing "I Dreamed A Dream" in the contest, a song she reprised for the final.
She had experienced a meteoric rise to fame over the past two months. Video footage of her singing her audition piece from the musical Les Miserables was posted on YouTube and received at least 100 million hits.
Despite expectations that Boyle would make a fortune from her talent and almost instant fame, there has been concern among the talent show's organisers about her ability to cope with pressure.
Boyle, who was starved of oxygen at birth leading to minor brain damage, has been pursued by the world's press since April and, according to show judge Piers Morgan, broke down in tears repeatedly during the run-up to the final.
She was reportedly spoken to by police after an outburst at the London hotel where she was staying, while Piers Morgan described her as "a frightened rabbit in headlights" and said she considered quitting.
