With just hours to go until Prince Harry and Meghan Markle tie the knot, there’s been plenty of speculation about who received a coveted invite to the royal wedding.

Around 600 people have been invited inside St George’s Chapel to watch the ceremony and attend an afternoon reception. Just 200 of them have been invited to a more intimate, private reception in the evening.

So who’s going?

George and Amal Clooney are among the A-listers attending the ceremony at Windsor Castle, according to People.

“Meghan and Amal have known each other for a while,” a source told the publication.

It’s understood the Clooneys are among the special guests who will attend the private evening reception at Frogmore House.

Other celebrities expected to attend include Serena Williams and her husband Alexis Ohanian, actress Priyanka Chopra, who is a close friend of Meghan’s, and several of her Suits co-stars, including Gina Torres, Sarah Rafferty and Rick Hoffman.

Jessica Mulroney, a stylist Meghan met on the set of Suits and soon became close friends with, and Lindsay Roth, another close pal, are also expected to be there. Mulroney’s children are in the bridal party.

Meghan’s friend Jessica Mulroney is attending, and her children are in the bridal party.

Meghan’s father Thomas Markle Sr had to pull out of the royal wedding because he had to undergo heart surgery, but her mother Doria Ragland will be there.

Meghan has several extended family members who have been publicly trashing her in the months leading up to the wedding. It’s obvious they are not invited.

Then there’s the royal family. Harry’s family will no doubt makes up hundreds of the guests. Prince William will be there as best man, Kate Middleton will be in attendance, and Prince George and Princess Charlotte are among the adorable flower girls and page boys who were announced as being in the bridal party.

Queen Elizabeth, Prince Phillip, Prince Charles and Camilla Parker Bowles are some of the other senior figures to look out for. It’ll be easy to spot Charles – Kensington Palace announced Harry’s dad will walk Meghan down the aisle.

Harry’s mum, the late Princess Diana who passed away in 1997, will be represented. All three of her siblings will be in attendance: Lady Jane FellowesLady Sarah McCorquodale and Earl Spencer.

In a move considered controversial by some, two of Harry’s ex-girlfriends, Cressida Bonas and Chelsy Davy both reportedly received invites.

And while he probably won’t attend the royal wedding itself, Meghan’s rescue dog Guy was spotted arriving at Windsor. With the Queen, no less.
