London: Popstar Lily Allen is "outraged" after coming to know that her rival Joss Stone has got an invite to Prince William and Kate Middleton`s wedding.
The 25-year-old singer, who failed to make it to the guest list of the much-awaited event, vented her anger on social networking website Twitter.
The `Smile` hitmaker was sure of making it to the guest list because she and Stone were both on the bill at the Concert for Diana in 2007, which was held to mark the 46th birthday of the prince`s late mother, the Princess of Wales.
"Well, you can quote me as `outraged`, why does Joss Stone get an invite and not moi (me)? I sang at the Diana concert too!" wrote Allen on Twitter.
The royal wedding which will be held on 29 April will have celebrities like filmmaker Guy Richie, singer Elton John, David and Victoria Beckham, `Mr Bean` actor Rowan Atkinson, photographer Mario Testino and socialite Tara Palmer-Tomkinson
