The couple - who tied the knot at St. George's Chapel on Saturday afternoon (19.05.18) - looked incredibly happy as they made their way to the nearby Frogmore House.

Kensington Palace wrote on Twitter: "The Duke and Duchess of Sussex depart Windsor Castle for a reception hosted by The Prince of Wales at Frogmore House, in a silver blue Jaguar E-Type Concept Zero. This vehicle was originally manufactured in 1968, and has since been converted to electric power #RoyalWedding (sic)"

Around 200 people are expected at the event this evening, which is being hosted by Prince Charles, Harry's father.

Earlier today, Queen Elizabeth held a lunchtime reception for Harry, Meghan and their 600 guests, where Prince Charles gave a "heartfelt" speech and said how "happy" he was for his son and the 'Suits' actress.

A source shared: "Charles gave a brilliant speech. Harry was very emotional. It was very sweet actually, very heartfelt. He said how proud [he was of who his son has] grown into. He ended it calling him, 'My darling old Harry, I'm so happy for you,' which was very sweet. He said how he's really happy for them both. He said he was very pleased to be asked [to walk Meghan down the aisle] and happy to help out."

Sir Elton John also performed at the reception as a "recognition of the close connection" he has with Harry.

Kensington Palace shared: "Sir Elton John has performed at the Lunchtime Reception for guests celebrating the Wedding of Prince Harry and Ms. Meghan Markle. Prince Harry asked Sir Elton to perform at the Reception which was hosted by Her Majesty The Queen at St George's Hall, Windsor Castle. Sir Elton performed for the newly married couple in recognition of the close connection he has with Prince Harry and his family."
