Boyle, who became a global superstar through video clip sharing website YouTube after her appearance on the 'Britain's Got Talent' talent show is 'much happier' following an anxiety attack, Gerry Boyle told ITV television.

The 48-year-old spinster was admitted to London's exclusive Priory clinic Sunday after suffering a shock defeat in the show's final the night before.

'She's much happier, she seems a lot more like herself,' Gerry Boyle said, adding that she was now staying in a London flat and had suffered an anxiety attack.

'Things are becoming clearer for her now. She's now beginning to believe that 'yes indeed, I will be a singer'.' She had been hot favourite to win with another rendition of 'I Dreamed A Dream", the song from the musical 'Les Miserables' which propelled her to fame, but was beaten into second place by urban dance troupe Diversity.

There were signs she was struggling to cope with the pressure in the run-up to the final and she was taken to the clinic Sunday in an ambulance after doctors assessed her under the Mental Health Act.

The Priory has declined to comment on individual patients.

Boyle is tipped to sign a lucrative recording contract following her success on the show. -- AFP
