Princess Anne celebrated her 75th birthday on Friday, August 15, with tributes pouring in from across the UK and beyond. Known as one of the most hardworking royals, the Princess Royal remains a firm favorite with the public — something reflected both in official celebrations and in the warm response to her latest portrait.

The palace released two photographs taken by John Swannell at her home in Gatcombe Park last month. In one, Anne wears a royal blue dress with a crisp white collar and buttons, standing gracefully by a window. In the other, she beams in a vivid red dress. “75 today! Thank you for all of your kind birthday wishes for The Princess this week,” the caption read.

Rather than a grand public event, Anne marked her milestone more quietly. Earlier in June she hosted a gathering at Buckingham Palace with representatives of charities close to her heart, while on her actual birthday she was expected to spend time sailing around the Western Isles of Scotland with her husband, Sir Tim Laurence.

Fans celebrate her image and work

The portraits quickly drew admiration online, with supporters praising both her style and dedication. “Happy birthday to our most beautiful and hardworking Princess!” one wrote. Others described her as “a jewel,” “classy,” “brave,” and “a credit to the institution.”
