Prince Harry overheard reacting to Meghan Markle dancing around their kitchen for her birthday

Meghan Markle celebrated her 45th birthday on Tuesday by jumping into a swimming pool with birthday balloons and dancing around her kitchen. 

In videos shared on her personal Instagram account, the Duchess of Sussex wore a white T-shirt reading "It's giving Mrs" while wearing a tiara as she twirled around her Montecito home. 

Meghan's husband, Prince Harry, 41, could be heard laughing in the background as he filmed. 

He joked, "Oh dear" as Meghan showed off her moves and sashayed around the room, before filming a breakfast spread of bagels, cream cheese and tomatoes.

Meghan then took over filming duties to capture their dogs, beagle Mia and black labrador Pula, wearing party hats for the occasion while giggling. 

Harry let out another "oh dear" as they tried in vain to get the dogs to sit for the camera, before giving up and removing the party hats. 

Meghan makes a splash for her 45th birthday

Earlier on Tuesday, Meghan shared two black-and-white photographs of herself jumping into a pool with her arms in the air and carrying her birthday balloons. 

Alongside the images, Meghan thanked her followers for their well wishes, writing simply: "Thank you for the birthday love!"

The celebrations were also marked by her lifestyle brand, As Ever, which paid tribute to its founder with a carousel of photographs, including a sweet childhood throwback.

"Happy birthday to our founder, @meghan," the post read, before adding a nod to one of the brand's signature candle fragrances: "Lighting No. 084 to celebrate!"

As was implied in her dancing video, Meghan appears to have spent her special day with Prince Harry and their two children, Prince Archie, seven, and Princess Lilibet, five, at the family's California home.

Meghan Markle's recent busy schedule

Meghan has been very busy in recent weeks with a series of exciting new projects. 

These included attending a screening for Cookie Queens last week, a documentary about the Girl Scouts, for which she serves as executive producer.

The event marked the Duchess of Sussex's first public solo appearance since she travelled to Geneva in May. Last month, she travelled to the UK with Prince Harry and reunited with King Charles, but was not publicly photographed. 

She also recently featured as a guest judge on MasterChef Australia and was even interrupted with a FaceTime call from Harry. 

Meghan showed her husband the delicious dishes prepared by contestants and said, "Hi, my love!" as she picked up the phone.
