The Duke and Duchess of Sussex will no doubt be preparing to celebrate Halloween with Prince Archie and Princess Lilibet this October.
But back when Prince Harry and Meghan were dating, the pair enjoyed a night out in Toronto where they "wanted to pull the pin on the fun grenade".
The Duchess previously revealed on The Ellen DeGeneres Show in 2021 how she and her then-boyfriend Harry had gone incognito to a post apocalyptic-themed Halloween party with Harry's cousin, Princess Eugenie, and Eugenie's future husband, Jack Brooksbank.
"The four of us just snuck out in Halloween costumes to just have one fun night out on the town before it was out in the world that we were a couple," Meghan said.
The pair then shared candid snaps from the party in their Netflix documentary, which was released last December. Find out which costumes they wore by watching below…
Harry also shared some insight into his Toronto night out in his memoir, Spare, released in January.
He wrote: "We invited Euge and Jack to join us for Halloween. And Meg's best friend Markus. Toronto’s Soho House was having a big party and the theme was 'Apocalypse.' Dress accordingly. I mumbled to Meg that I’d not had great luck with themed fancy-dress parties, but I'd give it another go."
He added: "For help with my costume, I'd turned to a friend, the actor Tom Hardy, before I left home. I'd phoned him to ask if I could borrow his costume from Mad Max.
"'The whole thing? Yes, please, mate!'
"The whole kit. He'd given it all to me before I left Britain, and now I tried it on in Meg's little bathroom. When I came out, she roared with laughter."
The day after the Halloween party, news of Harry and Meghan's romance broke, and the pair continued their relationship long-distance.
The Prince popped the question in the garden of his then Kensington Palace, Nottingham Cottage, and their engagement was announced in November 2017.
Harry and Meghan tied the knot in May 2018 at St George's Chapel, Windsor Castle. A year later they became parents with the arrival of Archie.
In January 2020, the Sussexes announced their decision to step back as senior royals and subsequently moved to the US, buying their first family home in Montecito, California. The couple's daughter, Lilibet, arrived in June 2021.
