Lily Allen's royal wedding 'outrage'

Lily Allen's been on Twitter to query why Joss Stone is going on Friday but she isn't.

The 25-year-old thought she might make it onto the guest list after appearing at the Concert for Diana in 2007, which was held to mark the 46th birthday of Prince William's late mother.

"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 guest list for Friday's event includes celebrities like Guy Richie,Elton John, David and Victoria Beckham, Rowan Atkinson and Tara Palmer-Tomkinson as guests.
