The only daughter of Princess Anne and Captain Mark Phillips, she is not technically a working royal like her cousins and works as a pro horse rider, even winning a silver medal at the 2012 Olympics as an equestrian.

Tindall, who is consistently ranked as among the most popular royals with the public, celebrated her 44th birthday on Thursday.

However, none of the official palace social media accounts marked Tindall’s big day following a policy change surrounding birthdays after the death of Queen Elizabeth II.

In 2022, royal aides announced the palace will only mark the birthdays of “working members” of the royal family on their official social media accounts.

Awkwardly, the snub came just days after Tindall appeared to break rank with the royal family after publicly commenting on the monarchy’s feud with Prince Harry and Meghan Markle.

Last week, Tindall attended the London Sporting Club lunch and candidly spoke about her feuding royal relatives.

“It is very hard to see from the outside, but 100 per cent, it is a family that is still going through the same struggles other people do,” the Olympian said, as reported by The Sun newspaper.

The down to earth Tindalls live on Princess Anne’s Gatcombe Park estate and share daughters Mia Grace and Lena Elizabeth and son Lucas Philip, who are similar in age to Prince George, Princess Charlotte and Prince Louis.

Tindall serves as godmother to future King George, while her brother Mark Phillips has increasingly become “like a brother” to Prince William after the Sussex feud.

She was also recently spotted attending the Bahrain Grand Prix alongside her other cousins Princess Beatrice and Princess Eugenie, as well her aunt the Duchess of York.

Meanwhile, her husband Mike Tindall has publicly defended his in-laws amid Markle’s claims about her struggles marrying into the royal family.

Reflecting on his own transition into royal life, the former English rugby star admitted it was “easier than it could have been”.

“Believe it or not, marrying into the royal family was pretty easy for me,” he wrote in his memoir, The Good, the Bad, and the Rugby: Unleashed, released in October.

In a passage many took to be a cheeky dig at Markle, he wrote: “They were always nice to me, and I was always nice to them. Simple really.”
