Susan Boyle has sparked fresh fears for her health after she scrapped a promotional visit to Australia due to fatigue.
The Scottish singer has already completed publicity tours of America and Japan and was due to fly Down Under next month (May10) to promote her music.
But the trip, which included an appearance at the Logie Awards, has now been cancelled, with Boyle's manager Andy Stephens insisting the star needs to take a break from her hectic schedule.
He tells the Sydney Daily Telegraph newspaper, "Regrettably, we have had to make the tough decision to postpone our Australian visit for the Logies in May. We want to apologise to all Susan's Australian fans and look forward to coming to Australia later in the year."
Boyle was admitted to a clinic in London shortly after she finished second in Simon Cowell's TV contest Britain's Got Talent, and was treated for exhaustion.
She hit headlines again when she was snapped sobbing and sucking her thumb following a promotional event in New York in November (09) and most recently raised concerns for her health after she collapsed at a London airport in February (10).
