Sarah Ferguson Celebrates Princess Eugenie's 34th Birthday: 'You Continue to Amaze Me Every Day' Other members of the royal family shared birthday messages for Eugenie on Sunday. The princess' mother, Sarah Ferguson, shared an Instagram post wishing her daughter a happy 34th birthday. “Happy birthday to my amazing daughter @princesseugenie,” Fergie, 64, wrote alongside a photo of the mother-daughter pair. “I am so proud of the incredible woman you have grown up to be.” “You continue to amaze me every day in your hard work, your grace, kindness, and the care you show to others,” the Duchess of York continued. “You will always be my silly, sweet, smart and thoughtful girl. I love you, Eugenie. Happy birthday.” Eugenie and her sister, Princess Beatrice, have together been supporting their mother after Fergie announced in January that she had been diagnosed with skin cancer. Shortly after the announcement, a friend of the Duchess of York told PEOPLE that her "family is rallying 'round” — especially her two daughters.

Dave Benett/Getty Back in November, Princess Eugenie spoke candidly about her motherhood experience during an appearance on the Table Manners podcast. She detailed the pressure she felt to "shake baby weight" after she gave birth to Ernest in May 2023. "I don't know about you, but on the post-baby body thing — it sends me mad, but I find it really hard to shake baby weight," Eugenie said. "I guess society dictates that you have to shake your baby weight and all that stuff." The royal also spoke on the podcast about the pressures of growing up in the spotlight and the media scrutiny of her appearance, saying it "definitely has caused a couple of issues around my relationship with having to look a certain way." "I guess everybody has that if you're in the public eye. I guess within our family, it happens at that perfect age where you're, you know, 13 years old and you've got that dorky bowl haircut and you're a bit chubby and you know, all the boys are bullying you and all that kind of stuff," she said.
