Princess Eugenie surprised royal fans by showing off a small tattoo as she joined her family for the second day of the Queen's Platinum Jubilee celebrations.
It's believed to be the first time she's had her inking, which appears to be a small circle or heart behind her ear, on display in public.
The Queen's granddaughter normally wears her hair down at official engagements, but half up, half down do for the Service of Thanksgiving at St Paul's Cathedral meant it was on display.
Eugenie joined Prince Charles, the Duke and Duchess of Cambridge and the Wessex family at the religious event today. Meghan Markle and Prince Harry were also in attendance, making their first royal appearance since quitting the royal family and moving to the US in 2020.
The younger York sister followed in the Duchess of Cambridge's footsteps by opting to wear a dress by one of her favourite designers, Emilia Wickstead.
She teamed the bright orange dress with a black hat and heels. She arrived with her husband Jack Brooksbank, sister Princess Eugenie and brother-in-law Edo.

And Eugenie isn't the only member of the royal family with a tattoo, and there have also been some fun royal piercings over the years.
Lady Amelia Windsor, the granddaughter of the Queen's cousin, Prince Edward, is a model and often shows off her tattoos in photoshoots and on Instagram.
She has a large tiger inked on her shoulder and tattoos on her wrists.
Looking back through the history books, there's also a former king who had some rather unexpected body art - which he got because he never expected to be on the throne.
King George V was on the throne from 1910 to 1936 after succeeding his father, King Edward VII. Up until 1892, Prince George was the second son and never expected to become king. It was thought that his elder brother Prince Albert Victor would rule.
When Albert Victor died from influenza, George had to leave his much-loved place in the Royal Navy and learn everything about his future role.
King George V would go on to become one of the most popular kings in British history as his reign took place during World War One.
As he never expected to be King, Prince George had been able to live the life of an ordinary Naval Officer for the majority of his younger years and, as a result, behaved just like everyone else.
Although it was never pictured, it is known that Prince George received a tattoo of a red & blue dragon while serving in Japan with the Navy in 1881. He later had a tiger inked onto his other arm.
Zara Tindall raised eyebrows in the 90s when she got her tongue pieced aged 17.
She famously revealed the silver stud to the royal family at Prince Charles's 50th birthday party, with her mum Princess Anne apparently not too bothered.
More recently Meghan Markle also joked about having a tattoo during a video to mark her 40th birthday. On a video call, comedian and actress Melissa McCarthy jokingly suggested that they got matching tattoos of their faces.
Meghan replied: "I've already has something similar across my back".
