Princess Eugenie shares rare royal selfie to celebrate Jack Brooksbank's birthday

Princess Eugenie has shared a rare royal selfie.

The Royal shared a photo to Instagram of herself and husband Jack Brooksbank cuddling up together in what appears to be Kensington Gardens, near their home at Ivy Cottage, on the grounds of Kensington Palace.

Clearly still in the honeymoon period, the newlywed gushed about her other half in the caption as she wished him a happy birthday.

"Happy Birthday to you, my one and only Jack," Princess Eugenie wrote.

"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'," she added sweetly. \

It marks Jack's first birthday since the couple married at St George's Chapel in Windsor Castle last October.

The second Royal Wedding of the year was a smaller affair than cousins Prince Harry and Meghan Markle's extravaganza but just as filled with love.

The night before the big day, the couple gave only their second joint interview about their wedding, admitting it's "nerve-wracking and a bit scary".

"But at the end of the day you get to marry the person you love," Princess Eugenie told ITV presenters and real life husband and wife, Eamon Holmes and Ruth Langsford.

Turning to her partner of seven years, the bride quickly added: "And you're going to be at the end of the aisle, and I'm going to be running towards you!"

"Eugenie has been amazing. She's been incredible, she has the ability to do a million things at once in her brain, including working as well as organising everything to do with the wedding," the groom gushed.

The couple began dating in 2011 after meeting while both were skiing in the Swiss resort of Verbier.

They announced their engagement in January 2018 before tying the knot that October.
