With a guest list more than 600 it was inevitable that the net would be cast quite wide and include pals from various parts of Harry and Meghan’s lives.
But there were some unexpected faces making their way into St George's Chapel earlier, so in case you’re wondering what the connections are, this is how all the wedding-goers made the cut.
James Haskell & fiance Chloe Madeley
As Prince Harry is an avid rugby fan and patron for the Rugby Football Union, he has been spotted joking around with the England player at a recent training session.
He got engaged to Richard Madeley and Judy Finnigan’s daughter in Paris last month
George and Amal Clooney
Meghan supposedly got to know Amal when she moved to Britain and they were introduced by a mutual friend.
They’re also rumoured to share a hair stylist, Miguel Perez.
David and Victoria Beckham
Harry has worked with David on many campaigns over the years, and Victoria has rubbed shoulders with Meghan, 36, on the fashion circuit.
James Blunt served in the army with prince Harry.
The You’re Beautiful singer once revealed that he was invited to the Invictus Games "[by] Prince Harry. By text. BOOM!”
The star TV host has apparently spent six hours with Meghan’s mum Doria Ragland talking for a tell-all interview.
Cressida Bonas and Chelsy Davy
Harry’s former blonde flames.
He had an on-off relationship with Chelsy between 2004 and 2011 and dated Cressie between 2012 and 2015.
James, 39, and Harry have been friends for years, and the Carpool Karaoke star reportedly bought the new Prince Louis a 23-book Beatrix Potter collection, said to cost around £540.
Both James and his producing partner Ben Winston have also made the guest list for the exclusive after party at Frogmore House tonight.
A close friend of Princess Diana and forever remembered for his rendition of Candle in the Wind at her funeral in 1997.
Following the death of Princess Diana in 1997, former Tory Prime Minister John Major was appointed special guardian to Princes Harry and William, responsible for legal and administrative matters.
The 75-year-old has watched over the Princes ever since.
