Meghan Markle, Prince Harry's wedding full of A-listers from George Clooney to Oprah to Serena Williams

Prince Harry's highly anticipated wedding to Meghan Markle is a star-studded affair.

The guest list ahead of the wedding was not made public, but as Saturday's event began, it became clear plenty of A-listers were in the crowd and dressed for the occassion.

Oprah Winfrey turned up at the church about two hours before the wedding in a pink feathered hat and a matching long-sleeve, knee-length dress. She walked in behind Idris Elba and his fiancée.

George Clooney and wife, Amal, arrived looking sharp in a classic suit while Amal shone in a yellow hat and matching dress. David and Victoria Beckham also filed into the church in matching black ensembles.

Earl Charles Spencer, Princess Diana's younger brother, arrived at about the same time as Oprah. James Blunt walked in a few moments later.

Elton John was spotted at the church as well. And Prince Harry's ex-girlfriend Chelsy Davy sat in the chapel in a black hat, looking serious as she waited for the ceremony to start.
