After Harry got permission from Queen Elizabeth to propose to Meghan in November 2017, he planned to surprise her with a proposal at a private dinner on palace grounds. But he gave himself away when he popped a bottle of magnum Champagne (which he doesn't drink) while she was roasting chicken.
Meghan, catching on, called a friend and said excitedly, "It's happening, it's happening!" when Harry went outside to bend down on one knee next to their dog Guy and 15 glowing candles he'd set up in the North Garden.
Meghan happily accepted his proposal (though Harry joked she had no choice because she had already moved her dog, Guy, over to London, and he was holding him "hostage").
The pair celebrated the proposal with friends. Everyone dressed in animal onesies, and Meghan and Harry wore penguin onesies because penguins mate for life.
