Celebrities arrive at Prince Harry and Meghan Markle's wedding

Amal and George Clooney, Ed Sheeran, and Victoria Beckham are among the celebrities rumoured and confirmed to attend Prince Harry and Meghan Markle's wedding.

Meghan Markle is a Hollywood celebrity in her own right, so it is no surprise that numerous A-lister Hollywood celebrities would be invited to her wedding to Prince Harry.

Oprah Winfrey and actor Idris Elba were among the first guests to arrive at Windsor Castle, the Washington Post reported. The Middleton family, Fergie [Sarah, Duchess of York] and Prince Harry's ex-girlfriends Chelsy Davy and Cressida Bonas are also among the crowd.
