The Duchess of Sussex, 41, was pictured picking up some food to go at the restaurant's drive-thru window in California on Sunday.
Meghan and Prince Harry have talked about their love for the burger spot since their move from the U.K. to Montecito, California. In fact, Meghan said it was her husband's "favorite" in an interview with Variety.
"There's one at the halfway point between L.A. and our neck of the woods. It's really fun to go through the drive-thru and surprise them. They know our order," Meghan told Variety.
"In-N-Out is the best! I order two double-doubles, animal style, fries and a Coke! And that's just for me! Meg gets the cheeseburger and fries with sides of jalapeños. I just stick with ketchup and that special sauce of theirs," he said. "So good!"
While Meghan was visiting In-N-Out on the West Coast, Prince Harry was in Germany for the sixth edition of his Invictus Games. The Duke of Sussex, who served in the British Army for 10 years, founded the adaptive sports competition for veterans and service personnel in 2014.
While he’s appeared solo at the 2023 Invictus Games so far, a spokesperson for the Duke and Duchess of Sussex previously confirmed that Meghan will travel to the event in Düsseldorf.
“The Duke and Duchess of Sussex are delighted to attend the Invictus Games 2023 in Düsseldorf.
However, Meghan wasn't far from Harry's mind at the opening ceremony on Saturday. In a speech, Prince Harry gave his wife a little shout-out. While recognizing the new nations joining the games — including Colombia, Israel and Nigeria — he explained that Nigeria definitely has a fan in his family.
"Now, I'm not saying we play favorites in our home, but since my wife discovered she's of Nigerian descent, it's likely to get a little bit more competitive this year," he said, referencing Meghan discovering that she is 43% Nigerian through a genealogy test, which she spoke about on her podcast Archetypes in October 2022.
Prince Harry and Meghan memorably made their public debut as a couple at the 2017 Invictus Games in Toronto, where she lived while filming Suits. Meghan has supported Invictus ever since, attending the Sydney games with her husband in 2018 (days after Kensington Palace announced she was pregnant with their first child, Prince Archie) and at The Hague in the Netherlands last spring.
She took the stage on both occasions, delivering remarks at the Invictus closing ceremony in 2018 and introducing Harry at the opening ceremony in April 2022, where they shared a sweet kiss.
