Sunday marked Meghan Markle [1]'s 38th birthday, and husband Prince Harry celebrated her special day [2] on Instagram! On Aug. 4, the Duke of Sussex gave his wife a shout-out by posting a photo of Meghan during their trip to Tupou College in Tonga [3] (where she notably fell into a fit of laughter [4] while listening to a choir sing about mosquitoes). "Wishing HRH The Duchess of Sussex a very Happy Birthday," the caption began, followed by a cake emoji. Prince Harry, 34, then added his own note, writing, "Happy Birthday to my amazing wife. Thank you for joining me on this adventure! - Love, H." So cute!

The past year has especially been a cause for celebration for the royal duo. Not only did they commemorate their first wedding anniversary [5], but they also welcomed their first child [6], a baby boy named Archie Harrison Mountbatten-Windsor [7], in May.
