NEW YORK (ES)Beyonce reportedly demanded £50,000 to attend a British summer carnival. The ‘Halo’ singer was invited to the annual Maldon Carnival Association in Essex, South East England, and organisers were thrilled when she took up their offer, as other stars, such as Britney Spears, Rod Stewart and Queen Elizabeth, hadn’t got back to them. Her spokesman in New York emailed committee boss Rob Slight saying: ‘’There is a possibility Beyonce will be available.’’
