Husband David, one of the ambassadors for the project, says he may work up the courage to ask Prince William for an invitation to the royal wedding if England is named as the competition host.
Along with William, president of the Football Association, and Prime Minister David Cameron, the star footballer has been in Zurich to present England's pitch.
"The engagement has come up in a few of the meetings, yes," he confirmed.
"I grew up in a family that was passionate about the royal family and a royal wedding will be fantastic for the whole country".
"I haven't asked for an invitation yet, but maybe if we win the bid I will".
