Ever since Meghan Markle has joined the royal family, she and Princess Eugenie have been good friends. Eugenie was one of the first royals to meet Meghan, even before she and Prince Harry revealed their relationship publicly, and the duo have formed a real friendship.
Up until Harry and Meghan moved to their own home in Windsor, the Sussexes were essentially "neighbours" with Eugenie and her husband Jack Brooksbank. The couples lived side-by-side in Kensington Palace for a while, giving the two newlywed couples time to support each other through the whirlwind!
