Star guests share photos from inside Princess Eugenie and Jack Brooksbank's gorgeous receptions!

After a traditional ceremony, Princess Eugenie and Jack Brooksbank celebrated their royal wedding on Friday, October 12 with two lavish receptions! Sprinkled amongst their royal guests, like Prince William and Kate Middleton, and Prince Harry and Meghan Markle, the lovebirds had a bevy of famous faces turn up on the special day. Stars like Demi Moore, Ayda Field and Robbie Williams and the Delevingne sisters all put on their finest attire for Queen Elizabeth's reception at Windsor and then the later bash at the grand Royal Lodge. And, fortunate for royal fans, many of them seemed to break the strict social media ban, sharing photos from the festivities on their Instagrams.

Love was in the air at Eugenie and Jack's luncheon reception. The newlyweds were captured sharing a sweet moment at the spectacular event, gazing adoringly into one another's eyes after their chapel vows. Making the rounds on social media, this snapshot also gives a glimpse of Queen Elizabeth's stunning reception room and the couple's autumnal cake in the background.

Prince Harry's ex-girlfriend Chelsy Davy took to Instagram to post a smiling selfie from the celebrations. It's thought to have been taken in between the day and evening receptions. Along with emojis, she captioned the cute snap: "Congrats Euge and Jack… thank you @jtmillinery for my lovely hat."
