Britain's Got Talent judge Simon Cowell has urged a missing woman who appeared on the show to contact someone.
Thelma Townsend and her husband appeared on the ITV programme last year with their whistling and dancing act.
The 62-year-old was last seen at her home in Withywood, Bristol, on Saturday.
Mr Cowell said he remembered Ms Townsend from her audition and added: "There are a lot of people very worried about you so please make contact."
Mrs Townsend is described as white, slim, about 5ft 5ins tall and has blue eyes and 'big' blonde/ginger curly shoulder-length hair.
She was last seen wearing a pink top and grey trousers, and may also be wearing a waist-length beige or brown jacket.
Anyone who has seen her is asked to contact the police.
