Meghan looks absolutely beautiful as she and Harry arrive for tea with the Queen and a rehearsal with the wedding party at Windsor Castle

Meghan Markle, Prince Harry, Prince William and Kate Middleton have all gone to Windsor Castle for rehearsals ahead of the royal wedding on Saturday.

The soon-to-be-married couple, who are meeting the Queen for tea today after their wedding rehearsal at Windsor Castle, were seen heading to Windsor Castle in a Range Rover escorted by police.

The American-born actress smiled as she arrived but her royal fiance looked far more serious. As they sped past crowds of well-wishers and up the famous Long Walk to oversee the last preparations for their wedding day, Meghan smiled and waved at them. 

Harry's brother William and his wife Kate were also seen leaving Kensington Palace for Windsor ahead of rehearsals this afternoon.

The Queen also traveled to Windsor from Buckingham Palace today before a teatime meeting and helped the couple with their final wedding preparations.

Meghan's mother Doria Ragland, who is set to give her daughter away in her father's absence, is also believed to be at the castle to meet the Queen for the first time hours after she was introduced to Prince Charles, Camilla, Kate and William.
