The Princess of Wales has received an unexpected show of support from one of Britain's most famous authors, days after secretly completing a grueling mountaineering feat.

J.K. Rowling, the creator of the Harry Potter franchise, publicly praised Catherine for her recent Three Peaks Challenge achievement in a social media post. The author shared a tribute to the Princess on X, formerly known as Twitter, commending her for raising awareness for cancer patients and their caregivers.

"Whether you're a royalist, republican, or couldn't care less, this not only acknowledged gratitude for those who support cancer patients, but absolutely made some unforgettable days for the hikers she met," Rowling wrote alongside a photograph of the Princess. Her message quickly gained traction among royal observers and fans alike.

The tribute follows a meeting between Rowling and Queen Camilla at the Palace of Holyroodhouse in Edinburgh on Tuesday. Buckingham Palace released an official photograph of the pair, noting their shared passion for books and commitment to encouraging children to read. Both the Queen and the author are also known advocates for supporting victims of domestic and sexual abuse .

However, the royal household has faced criticism for the Queen's public engagement with Rowling. The author has been a polarizing figure in recent years, facing backlash over her outspoken views on gender identity issues. Despite this, the Palace proceeded with the meeting and public endorsement.

The meeting came on the same day the Princess of Wales quietly resumed her official duties. Catherine, 44, held a private engagement at Windsor Castle, meeting with Australian philanthropist Nicola Forrest, a co-founder of the Minderoo Foundation. The Princess is a patron of the Royal Foundation, which supports charitable initiatives focused on mental health, conservation, and early childhood development .

The Princess appeared in high spirits as she returned to work just days after secretly completing the National Three Peaks Challenge. The demanding trek involves climbing the highest peaks in Scotland, England, and Wales—Ben Nevis, Scafell Pike, and Snowdon—typically within 24 hours . Her achievement has drawn widespread admiration for her physical endurance and commitment to supporting cancer-related causes.

Catherine was treated for cancer earlier this year and has gradually been returning to public life. Her successful completion of the challenge and her warm reception of the Australian philanthropist mark significant steps in her phased return to royal duties.
