Meghan Markle has offered the world an intimate window into life behind palace gates, or rather, behind the sunny walls of their Montecito home, with a deeply personal and touching tribute to Prince Harry in celebration of Father's Day.

One photo shared by Meghan showed the family of four adorably sporting mouse ear hats. The Sussexes celebrated Lilibet's fourth birthday at Disneyland Resort. Meghan included a photo of her daughter's impressive Little Mermaid cake, as well as an image of Minnie and Mickey Mouse plush toys with a "Happy Birthday" pin for Lili and a "1st visit" pin.
