“Happy Birthday to you, my one and only Jack. You are one of a kind and totally extraordinary. Nine birthdays and counting…to quote you from a few months ago ‘you light up my life’ 🎂🎈🎉🎊,” Eugenie captioned the candid shot.

The black shades with white circles around the lenses appear to be a favorite of the royal’s – she also wore them to theAugust wedding of Charlie van Straubenzee and Daisy Jenks.

Princess Eugenie, 29, went a similar route to mark Jack’s birthday last year, posting a photo of Jack laughing so hard that his eyes are squeezed shut.
“Clearly I said something funny this time! Sums up Jack in a nutshell!” she wrote.

The couple, who announced their engagement in January 2018, met when Eugenie was attending Newcastle University and vacationing in the Swiss ski resort of Verbier with friends. Mutual pals introduced the two on the trip.
Eugenie said in an interview with BBC 1’s Matt Baker that it was “love at first sight” — and Jack agreed.
“We met when I was 20, he was 24,” she said. “[We] fell in love. We have the same passions and drive for life.”

During the couple’s October wedding reception,Andrew had a little fun at his new son-in-law’s expenseduring his speech and had the crowd chuckling.
“The Duke told a story about their dog Jack [a Norfolk terrier],” a source at the wedding tells PEOPLE. “One day, I think it was early in the relationship, he shouted, ‘Jack, get off the chair!’ And the dog didn’t move. But Jack did!”
