Princess Eugenie married her fiancé Jack Brooksbank in a stunning ceremony held at St George's Chapel in Windsor this morning, and a flurry of celebrity guests attended her big day.
As celebrities including Robbie and Ayda Williams, Ellie Goulding, James Blunt, Jimmy Carr, Naomi Campbell, Kate Moss and Cara Delevingne entered the stunning church, X Factor judge Robbie Williams broke a MAJOR rule.
Just like David Beckham did back in May at Prince Harry and Meghan Markle's wedding, former Take That singer Robbie was caught chewing gum in the church, something which is seriously frowned upon by the Royals.
Oh dear! 🙈
Earlier in the day, as Robbie arrived with his wife Ayda and mother-in-law Gwen Field, the singer was forced to run after Gwen's hat as Storm Callum hit Windsor, causing chaos for the guest's outfits.

Robbie and Ayda have been friends with newlyweds Princess Eugenie and Jack Brooksbank for a number of years, with their six-year-old daughter Theodora acting as one of the bridesmaids in today's ceremony.
Theodora, who goes by the name Teddy, joined Princess Charlotte, Prince George and Sophie Winkleman's daughter Maud in the church, with the Royal children looking cute as ever.
As well as the celebrity guests, a further 1,200 members of the public, selected by ballot, listened to a live broadcast in the castle grounds.
