The news comes a day after Wills and Kate sent the former Suits actress a sweet message for her 38th birthday.
The post on Kensington Palace's official Instagram page read: “Wishing a very happy birthday to The Duchess of Sussex today!”.
The Cambridge’s selected a snap of Prince Harry, Meghan, William, Kate and Prince Charles.
The post has quashed any rumours of a royal rift between the royal foursome for now.
Harry also took to Instagram to wish his wife and mother of his child Archie Harrison a happy birthday.
“Happy Birthday to my amazing wife. Thank you for joining me on this adventure! - Love, H”.
An insider revealed that Meghan held "low-key" celebration at Frogmore Cottage yesterday.
