Susan Boyle, who is reportedly worth several million pounds, has applied for 6.31 pound-an-hour minimum wage position at Ladbrokes store.
The 52-year-old singing sensation saw the job ad in a shop window and then walked in to quiz staff about the role, a newspaper reported.
Deputy manager David Corr said that Boyle walked into the shop and asked about the job advertised in their window, asserting that the happening shocked everyone present.
However, once the staff got over their bemusement, they told the star that she would need to apply online.
A job description explains that the role is an entry-level role which requires the person to act as the first point of contact with the customers.
