Connie Fisher has been forced to pull out of a stage production of The Sound Of Music because she no longer has the vocal range to play Maria.
The 28-year-old – who shot to stardom in the BBC talent show How Do You Solve A Problem Like Maria? – said her voice had undergone a radical change as a result of a throat condition.
Connie said: "After many months of battling with a throat condition, known as congenital sulcus vocalis, my vocal range has altered dramatically.
"My journey with this amazing show has been such a magical one and I am devastated that I am not able to close the tour."
The star had previously taken the lead role on stage at the London Palladium.
She'd been expected to tour with the production to Cardiff, Manchester and Newcastle.
In 2009, Connie had to call off a 14-date Secret Love UK tour after being advised to have immediate surgery on her vocal cords by specialists in the US.
The former call centre worker will be replaced by Verity Rushworth as Maria at the Wales Millennium Centre, when the production opens there later this month.
And Jason Donovan will star as Captain Von Trapp.
Her spokeswoman later confirmed that she would never play the famous role again as her voice has changed permanently.
Instead, she'll be concentrating on other work.
