Meghan Markle is celebrating her 45th birthday today in playful style. The Duchess of Sussex shared two black and white photographs on Instagram of herself jumping into a pool with a bunch of balloons. “Thank you for the birthday love,” she wrote, adding a balloon emoji.

In July, Meghan shared snaps from her family’s vacation to Portugal and the UK (including a visit to Princess Diana’s childhood home, Althorp), where she appeared to be wearing the same bathing suit as she did in today’s birthday post, a black square-neck one-piece from Hunza G.

Her brand, As Ever, also celebrated her birthday with a series of photos on its account, writing, “Happy birthday to our founder, @meghan 💌 Lighting No. 084 to celebrate!” (As Ever’s “Signature Candle No. 084” is named for her birthday, August 4, and features notes of fresh water lotus, earthy sandalwood, and California poppy.)

Meghan is not the only royal woman with an August 4 birthday: Queen Elizabeth, the Queen Mother, also celebrated her birthday on the 4th—and this fact reportedly delighted King Charles when he discovered the coincidence during a summer vacation eight years ago, according to Prince Harry’s memoir, Spare.

“Towards the end of summer 2018 we went to Scotland, the Castle of Mey, to spend a few days with Pa,” Prince Harry shared of the moment in Spare. “The bond between Meg and Pa, always strong, grew even stronger during that weekend. One night, over pre-dinner cocktails, Fred Astaire playing in the background, it emerged that Meg shared a birthdate with Pa’s favorite person: Gan-Gan. August 4. Amazing, Pa said with a smile. At the memory of Gan-Gan, and the link between her and my bride, he suddenly became buoyant, telling stories I’d never heard, essentially performing, showing off for Meg.” Since the Queen Mother’s death in 2002, Charles has spent the first week in August at the Castle of Mey before heading to Balmoral.

In addition to her Instagram post, Meghan also posted two videos on her story. One is of her in white pants with a shirt that reads “It’s Giving Mrs.”

She also wears a happy birthday crown as she dances around her kitchen. Giant balloons, some heart shaped, are on the counter.

As she grooves in her kitchen, it appears bacon is cooking in a pan next to a plate of bagels and toppings.

In the second Instagram story video, Meghan laughs as she and Prince Harry struggle to keep party hats on their dogs, beagle Mia and black Labrador Pula.

Mia is seen laying down with a party hat on her head, but unsuccessfully keeping it on.

“Oh dear,” Harry can be heard in the background.

Pula is also nearby, wagging her tail with the party hat in her mouth. Ultimately, Meghan opts to remove the hats from her pups.

Meghan’s birthday comes weeks after she posted photos from her summer holiday. Her vacation pics included a visit to her late mother-in-law Princess Diana’s childhood home, as well as trips to the beach and quality time with husband Harry and their two kids, Prince Archie and Princess Lilibet.

The family traveled to the U.K. in July, with Harry attending a series of events to promote the 2027 Invictus Games. They then reunited with King Charles III and Queen Camilla, who hosted the foursome at Highgrove House, their private residence in Gloucestershire, England, Buckingham Palace confirmed to NBC News.

This marked the first time the king had seen his grandchildren in four years.
