VIDEO & PHOTOS: Prince William & Kate Invited Their Exes To The Royal Wedding! New Details About The Guest List

As the crowd cheered, Prince William and Kate Middleton visited young people in northwestern England Monday on their last official trip before they wed later in April.

Under rainy skies, the couple was on hand for the official opening of the Darwen Aldridge Community Academy, an independent non-fee paying school that specializes in entrepreneurship. (The school actually opened its doors in September, 2008.)

In a sharp break with royal tradition, Prince William has invited a number of his aides to the reception. Among them are two of his former nannies, his press officer, his private secretary and his personal secretary. Also invited is William's former headmaster from the Ludgrove School, the provost of Eton College, and William's housemaster at Eton College.

The couple, who visited the Caribbean island of Mustique in the past, included some of the locals on the wedding guest list. The owners of the villa where the couple stayed, the island's head tennis coach, yoga teacher, doctor and the owner of Basil's Bar all received invitations, along with the owners of the villa where William and Kate previously stayed.

Among William's friends at the wedding will be a number of former Etonians, including banking heirs James and David Jardine-Paterson, polo player Ben Vestey and his wife Chloe, and Thomas van Straubenzee, who is expected to assist Prince Harry with the best man's speech, along with his younger brother Charles.

William's best friends from Gloucestershire are all on the list, including all of the Duke of Northumberland's children, polo player Captain Jack Mann, Olympic gold medalist Richard Meade, and Susanna and Jake Warren, the grandchildren of the Queen's former racing manager, the Earl of Carnarvon.

Several members of William's inner circle of friends, including Guy Pelley -- who helped organize the bachelor party -- will attend the wedding along with his mother, father and two brothers; millionaire Arthur Landon and his mother Katalina will also be in attendance.

The couple's friends from St Salvator's residence hall at St. Andrew University have been asked to the evening reception. The guests include Virginia Fraser, neighbor of the couple while at St. Andrews, and former roommates Olivia Bleasdale, Oli Baker and Fergus Boyd. The Prince and Miss Middleton have also invited Sir Henry Cheape, who owns the Strathtyrum Estate in St Andrews where the couple shared a farmhouse.

In a move that may surprise some people, it appears as if both William and Kate have invited their exes to the royal wedding. Rupert Finch, whom Kate dated briefly at St. Andrews and her rumored high school boyfriend, Willem Marx will attend, along with all of William's former flames: Isabella Anstruther-Gough-Calthorpe, Jecca Craig, Arabella Musgrave, Olivia Hunt and Davina Duckworth-Chad.

Kate's sister, Pippa will bring her boyfriend of one year, Alex Loudon, while her brother will go to the wedding solo.

Prince Harry has not revealed if he will have a date to the wedding, but The Mail on Sunday confirmed that his on-and-off girlfriend Chelsy Davy has been invited to the wedding and the evening reception.

As RadarOnline.com previously reported, David and Victoria Beckham and Sir Elton John also received invitations. Two people who did not receive invitations include President Obama and wife Michelle.

William and Kate will wed Friday, April 29 at Westminster Abbey.

It's estimated nearly 2 billion people worldwide will watch the wedding.
