David and Victoria Beckham(06 of18)
Open Image ModalA close friend of Prince Harry's, there was no way that David and Victoria would not be at the royal wedding, having previously attended William and Kate's ceremony in 2011.

George and Amal Clooney(07 of18)
Open Image ModalA union of the British royal family and the world of acting? Seems like the perfect event for actual Hollywood royalty George Clooney and his always-impressive human-rights-lawyer-turned-red-carpet-must-see Amal.
Meghan Markle’s friendship with Amal Clooney was revealed by their shared hairstylist, Miguel Perez, who told The Mail: “I do Meghan's hair [and] I do Amal's, and Meghan is friends with her. Amal put Meghan and me together when she moved here [to London]. I do her colour, her cut and her styling.”
We do love an A-list friendship based on hairstyling. (credit:PA Wire/PA Images)

Sir Elton John and David Furnish(09 of18)
Open Image ModalSir Elton and his husband were seen leading a conversation with the Beckhams, as well as James Blunt and his wife, Sofia Wellesley.
Of course, Sir Elton’s relationship with the royals, in particular Princes William and Harry, goes way back, as the singer was close with their late mother, Princess Diana, even famously performing a rewritten version of ‘Candle In The Wind’ at her funeral. (credit:REX/Shutterstock)

Priyanka Chopra(11 of18)
Open Image ModalThe India-born actress is one of Meghan's most famous friends, so it was a dead cert that she would be at the wedding, where she made her way in with the cast of 'Suits'.
Here she is with Abigail Spencer who, incidentally, could probably teach Victoria Beckham a thing or two about how to enjoy oneself at a wedding. (credit:James Gourley/REX/Shutterstock)
Patrick J Adams(12 of18)
Open Image ModalPatrick famously played Meghan's on-screen husband in 'Suits', and has been one of her biggest public supporters since her relationship with Prince Harry began.
He tweeted the night before the wedding: "Meghan - wherever you are - we are so grateful to be here to watch you both take this monumental step together. Love deeply and live well." (credit:James Gourley/REX/Shutterstock)
James Corden(13 of18)
Open Image ModalJames was another of the celebrity friends of Prince Harry at the wedding, along with his wife Julia Carey.
Hilariously, after getting Victoria Beckham to confess that she'd been invited during an interview on 'The Late Late Show', James claimed that he'd been snubbed, which was either a lie to throw us off the scent, or a hint to the royal family that he wanted to come.
Either way, mission accomplished. (credit:REX/Shutterstock)

Cressida Bonas(16 of18)
Open Image ModalBefore getting together with Meghan, Cressida was Prince Harry’s most famous ex, who he met through his cousin, Princess Eugenie.
The two dated on and off for a number of years, including a number of official royal engagements, and remained on good terms when they split in 2016.
Reports suggested at the time that Cressida’s struggle to cope with the scrutiny of being in the public eye that came along with dating such a famous figure was the reason for the break-up.
She’s now in a relationship with chartered surveyor Harry Wentworth-Stanley, both of whom are expected to attend the wedding of Princess Eugenie later on in 2018. (credit:REX/Shutterstock)
