Hollywood's hottest stars, sporting gods and A-lister music celebrities are among the guests at today's royal wedding.
Football star David Beckham and wife, Spice Girl Victoria, held hands as they walked towards St George's Church at Windsor Castle.
And there was a big roar from the crowd as actor George Clooney arrived with wife Amal - dressed head to toe in fetching yellow.
Talkshow queen Oprah Winfrey waved at the crowd as she arrived wearing a light pink ensemble with matching hat.
Luther star Idris Elba arrived at the same time with partner Sabrina Dhowre.
Singer Sir Elton John has also been spotted, as has British singer James Blunt, actor Tom Hardy, actress Carey Mulligan with husband Marcus Mumford and singer Joss Stone.
It was confirmed earlier this week that Sir Elton would perform at today's ceremony - 21 years after he gave a moving tribute at the funeral of Prince Harry's mother Diana, Princess of Wales.
Tennis champ Serena Williams and husband Alex Ohanian have been sighted making their way into the chapel.
British comedian and Carpool Karaoke star James Corden is among wedding guests.
The Spencer family are also represented by Charles Spencer - Diana's brother - and his wife Karen.
The Duchess of Cambridge's family, the Middletons, have also turned up. Kate Middleton's younger sister, Pippa, was all smiles alongside husband James Matthews. The couple are expecting their first child.
While Prince Harry's aunt, Sarah Ferguson, has made it to the party also.
Like no other royal wedding before it, the wedding will be sprinkled with stardust from the glittering LA-set. Friends from Meghan Markle's inner circle - including actors from her hit television show Suits - will give the wedding a touch of "LA cool".
Green smoothies as much as vintage champagne may just be the drink of choice.
Tennis superstar Serena Williams and her husband were also on the guest list.
The stars of Suits, the law drama Marjkle starred in were also there, including her former on-screen boss Gabriel Macht, aka Harvey Spector.
This week, Patrick Adams, Markle's on-screen husband, posted an Instagram photo from a pub in nearby Beaconsfield, Bucks, writing: "I have historically ale'd."
The host has been spotted across the Atlantic post-election.
