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." However, it later emerged the 'Crazy in Love' hitmaker was demanding a huge fee just to attend, something the carnival could not afford. Her spokesman said: "It is apparent there is some miscommunication. Beyonce will require an appearance fee." An annoyed Rob said: "We had wanted this year to be the best yet." But Beyonce will be in Essex over the summer as it was recently announced she will headline this year's Virgin Media V Festival. The mother-of-one will make her only European festival appearance while Kings of Leon will also top the bill at the annual event, which takes place in both Hylands Park, Chelmsford, and Weston Park, Staffordshire across the weekend of August 17 and 18. Tickets for this year's event go on sale at 9am on Friday March 1. Visit www.vfestival.com for more information.
