Singer Brian McFadden has joked that he could gatecrash Britain's royal wedding with Lily Allen, since neither of them were invited to the ceremony.

Allen had previously voiced her outrage at not being included on the guest list for the wedding of Prince William and Kate Middleton.

In a posting on Twitter, McFadden suggested to Allen: "We could gate crash."

"I heard they have kfc hot wings at the buffet! And I think(not certain) that it's a free bar. (sic)"
