And now, rumours are swirling that the Made In Chelsea star may have been snubbed by the groom.
According to the Mail on Sunday, Harry had become highly suspicious of Meghan’s ‘blabbermouth’ friend.
‘Harry warned Meghan off Millie. He seemed to believe she was a blabbermouth and better off out of the loop,’ a source revealed.
‘Harry doesn’t often tell Meghan what to do, but he put his foot down.’
On the big day, Millie posted photos on social media of herself watching the ceremony from her sofa.
Meghan and Millie are believed to have met a year before the Duchess started dating British prince and were pictured together at luxury hotel Soho Farmhouse.
