The best part of the royal wedding was arguably the people-watching.

The royals were joined by some fairly famous faces yesterday, including David and Victoria Beckham, James Corden, Elton John and James Blunt. A number of Meghan's friends also made the trip over from America for the occasion and we were loving watching them take in all the pomp and ceremony of the day. Serena Williams, a close pal of Meghan's, was there with her husband Alexis Ohanian and couldn't help but share snippets of the day with her followers via her Instagram stories. While she didn't (and probably couldn't) post from inside the ceremony or the reception, she did uploads clips of herself and other guests being bussed into Windsor at the start of the day. She also shared a video of herself having ditched her heels after the ceremony, with her hubby dutifully carrying her shoes for her. The couple took a break from the wedding in the afternoon before the evening reception and went for a stroll around the castle grounds with eight-month-old daughter Alexis. Priyanka Chopra, another friend of Meghan's, was there too and posted a heartfelt message to the happy couple. "Every choice made at this wedding by you both will go down in history, not just because it was your wedding but because this incredible wedding stood for change and hope," she wrote on Instagram "Both things that the world needs desperately. Thank you for being the perfect picture of all things good.. seeing your union and love blessed in front of my eyes Made me so happy.. and tear up!" Also in attendance were some of Meghan's former Suits co-stars. "Congrats to Meghan and Prince Harry on your nuptials. Enjoyed meeting many of your family and friends and an incredible honor to be a part of the whole celebration," Gabriel Macht, who plays Harvey Spectre on the show, shared. Rick Hoffman, who plays Suits' Lewis Litt, posted a brash video to his Instagram explaining that he looked unimpressed during the royal wedding because the person sitting next to him had bad breath. Charming.
