Britain's Got Talent star Susan Boyle was dropped from the show's touring concert last night after she was spotted on a balcony shouting about her cat, pebbles.

The 48-year-old singer has struggled to cope with media pressure since her rise to fame a few weeks ago, culminating in her being admitted to The Priory with exhaustion after the series ended.

While she managed to perform with the rest of the show in Edinburgh, not far from her hometown of West Lothian, on Tuesday, her strange behaviour has seen her being axed from the rest of the tour.

Most recently she was spotted on the balcony of her eighth floor room overlooking the atrium at Radisson SAS Hotel in Liverpool shouting for her beloved cat, Pebbles.

According the The Mail.com, fellow hotel guests claimed Susan was seen bawling: 'Where's my cat?' on the balcony on Thursday afternoon.
