Princess Eugenie Debuted a Tattoo Behind Her Ear at Queen's Platinum Jubilee Celebrations

Princess Eugenie appears to be sporting some new ink.

Queen Elizabeth's granddaughter took part in the monarch's Platinum

Jubilee celebrations last week, including a service of thanksgiving at St. Paul's Cathedral.

At the event, she appeared to debut a small circular tattoo behind her ear, which she showed off by her half-back hairstyle and black fascinator.

Princess Eugenie, 32, may be the highest person in the British line of succession to the throne with a tattoo.

While it's uncommon for British royals to have ink, Amelia Windsor, the

granddaughter of the Queen's cousin the Duke of Kent, is an exception

with her various tattoos including three bear cubs,

a tiger on her left shoulder blade and a petal on her rib cage.
