But during the weekend’s Trooping the Colour, Princess Eugenie, who is eighth in line to the throne, threw caution to the wind and posted a photo revealing the hallowed halls inside Buckingham Palace itself.
The rare glimpse beyond the balcony pictured her father, Prince Andrew, who was recently given the additional title of Colonel in Chief of the Grenadier Guards, news.com.au reports.
“A wonderful and proud day celebrating Her Majesty’s birthday and @hrhthedukeofyork for his first Trooping the Colour as Colonel of the Grenadier Guards,” Princess Eugenie captioned the photo.
Princess Eugenie made her Insta-debut on International Women's Day with a video of herself speaking at the SSE Arena to raise awareness of scoliosis, which she was diagnosed with as a child.
