Sam Bailey was forced to pull out of her pantomime appearance after a ladder fell on top of her and knocked her out cold - as she retrieved a suitcase from her loft.
The former X Factor star was carried off in ambulance and deemed too unwell to take to the stage as the Enchantress in Beauty and the Beast.
40-year-old Sam had been due to performing at De Montfort Hall in Leicester before her nasty injury.
A spokesperson for the singer said Sam was knocked unconscious when the loft ladders sprang back and hit her on the head.
"Sam had got a suitcase out for her daughter Brooke who is going on a skiing trip," said the source.
"Her husband Craig was there and called the ambulance but Sam was on the floor for about an hour.
"Sam was checked over at Leicester Royal Infirmary then allowed home later that day," they added.
The singer, a former prison officer at HMP Gartree near Market Harborough, has tweeted pictures of herself on a stretcher with a neck brace on.
Sam also posted a photograph of herself on her sofa at home wearing pyjamas and a dressing gown and cuddling two dogs.
She tweeted: “I’m on the mend people!”
