Meghan Markle Shares Smoldering Throwback of Prince Harry on His 41st Birthday: ‘Oh Hi, Birthday Boy’

Meghan Markle is getting flirty with Prince Harry on his 41st birthday.

The Duke of Sussex turned 41 on Monday, Sept. 15, and his wife celebrated with a new post on her Instagram page, sharing a photo of Harry from his 31st birthday a decade ago — before he and Meghan met! — when he visited Goodwood Aerodrome. The visit marking the 75th Anniversary of the Battle of Britain included a historic flypast featuring Battle of Britain aircraft.

The snap showed Harry wearing a green jumpsuit with the name Harry Wales, using his father King Charles’ then-title as the Prince of Wales as his surname, as he and Prince William did during their time in school and the military.

Meghan cheekily captioned the post, “Oh hi, Birthday Boy 🔥”

The Duchess of Sussex, 44, launched her Instagram account in January and has since used the profile to celebrate special occasions and mark milestones, including a tribute to Harry on Father’s Day and posts for the birthdays of their children, Prince Archie, 6, and Princess Lilibet, 4.

In February, Meghan dedicated a romantic post to Harry on Valentine’s Day and posted a black-and-white snap of them kissing.

“Back home taking care of our babies, and missing my Valentine, as he continues on at the Invictus Games, changing lives and reminding all of us of the power of healing and resilience through these incredible veterans and their families. Beyond proud of my husband and what he’s created,” she wrote below the photo at the time.

“My love, I will eat burgers & fries and fish & chips with you forever. Thank you for you,” Meghan said. 

She added the hashtag #lovewins — quoting the close of the speech she made at her royal wedding to Harry in 2018 — and signed it “As ever, M,” in an Easter egg before the launch of her lifestyle brand, As ever.

Prince Harry and Meghan married in May 2018 and became parents when their son, Prince Archie, was born in May 2019. 

The couple stepped back from their royal roles in the U.K. in 2020 and moved to Meghan’s home state of California in the U.S., where Princess Lilibet was born in June 2021.

Exclusively speaking to PEOPLE at the Invictus Games Vancouver Whistler 2025, Prince Harry opened up about what it meant to have Meghan by his side there. 

The 2025 Invictus Games were the seventh cycle of the international adaptive sports tournament Prince Harry founded in 2014 to support wounded, injured and sick service members and veterans, and the competition in Canada took him and Meghan back to a country that’s central to their love story.
