Pippa Middleton has one of the most famous mommies in the world for a big sister, but when it comes to pregnancy inspiration, there鈥檚 another celebrity she鈥檚 turning to for tips: Serena Williams.

In her new column for UK supermarket publication Waitrose Kitchen, the mommy-to-be, who confirmed her pregnancy in the same outlet early last month, revealed that she鈥檚 taking her exercise cues from the US tennis pro.

鈥淚鈥檝e been a tennis fan since childhood, as a player and spectator, and have been keen to continue playing safely throughout my pregnancy,鈥 she wrote in the piece. 鈥淭ake Serena Williams. She famously proved that women can play a high level of tennis from two months (when she won the 2017 Australian Open) up to eight months. Few of us can relate to this elite excellence, but if you鈥檙e a healthy, well-trained player with an uncomplicated pregnancy, there鈥檚 no reason why you can鈥檛 continue a good level of tennis.鈥

Still, Middleton, 34, IS taking precautions, noting that she would be refraining from leaping after balls and avoiding sharp turns and quick movements, especially near her due date. As she revealed in a previous column, she also planned to cut back from her regular four-to-five-day training sessions each week.

Middleton鈥檚 admiration for the athlete isn鈥檛 completely arbitrary, as Williams has several connections to the royal family: She attended the royal wedding of Prince Harry and Meghan Markle back in May and was been seen supporting the prince alongside Markle at a polo match just this weekend.
