Whilst a further statement from Kensington Palace added: "Ms. Meghan Markle has asked His Royal Highness the Prince of Wales to accompany her down the aisle of the Quire of St George's Chapel on her Wedding Day".
Sarah, who plays Donna Paulsen in the hit drama, revealed that watching Meghan say "I do" was a very proud moment for her.

Meghan Markle and Prince Harry have officially asked that their friends and supporters donate to charity in lieu of sending them traditional wedding gifts.
Meanwhile, the Duke and Duchess of Sussex are reportedly returning over $9 million worth of wedding gifts in accordance with royal guidelines.
