Susan Boyle was mistaken for Britain's Queen Elizabeth last week.

The Scottish singer - who had been travelling first class from Paris into London with her manager Andy Stephens and niece Kirsty Foy - found the case of mistaken identity highly amusing after Eurostar staff bowed and curtseyed to her after being told to expect a royal passenger

An onlooker at the Gare du Nord station said: "A rumour went round that the queen had arrived to catch a train back so everyone was told to observe royal etiquette.

"It soon became clear it was Susan - and not Her Majesty - but one train attendant still thought she was the queen. Susan roared with laughter when she realised the mix-up."

Susan, 48, was travelling back from a hectic promotional tour, which included a performance at Italy's Sanremo festival and an appearance on a French TV show and the confusion provided a much-needed boost for the tired star.

A source said: "She'd had a pretty hectic few days, but this really cheered her up."
