Susan Boyle fans were seeing double yesterday when the star unveiled her likeness at Madame Tussaud’s. The wax model dons an elegant black outfit donated by the Scottish singer. It’s the same outfit she wore in the video for her cover of The Rolling Stones’ Wild Horses. The 50-year old star joked that the only person she would choose to stand next to her waxwork is Simon Cowell. Boyle’s wax model is on display at the new Blackpool branch of Madame Tussauds which opens to the public on Thursday in the Lancashire resort.
