Princess Eugenie was the only member of the York family who didn't attend the royal wedding of Lady Gabriella Windsor and Thomas Kingston on Saturday, but that didn't stop the 29-year-old from sending a special message to her cousin on her big day.

Eugenie and her husband Jack Brooksbank got married at the same venue just seven months ago, and were unable to make the ceremony due to an already-booked holiday, HELLO! understands.
