Princess Eugenie Calls Husband Jack the 'Ultimate Father' Sharing Cuddling Pics with Son August

Princess Eugenie honors her husband for Fathers Day with a beautifully captioned Instagram photo of her husband pushing their newborn in a pram.

Princess Eugenie, 31, and granddaughter of Queen Elizabeth shared the beautiful photo of her husband Jack Brooksbank pushing their 4-month-old baby August Philip Hawke for a father's Day celebration.

A second photo showed Princess Eugenie with their baby in a sling, and the couple all smiles. A third photo showed Brooksbank with his son closely cuddled to his neck and the fourth one of him taking a nap with the baby on his chest.

This year's Father's Day is extraordinary for Brooksbank as it is his first as a dad. Brooksbank, 35, and his wife, Princess Eugenie, welcomed their baby boy on February 9 in the Portland Hospital in London.

This is the very same hospital where the princess was delivered. Alongside the beautiful photos, Eugenie captioned a sweet message to her husband that said:

"Happy Father's Day to you, my love.. you are the ultimate father to our boy!!"

In a different Instagram post, Princess Eugenie explained why they named their baby August Phillip Hawke Brooksbank. But before she did, she thanked her fans for their sweet messages.

In the caption, the princess said that August was in remembrance of Queen Victoria’s husband, whose middle name was Augustus. Phillip is Eugenie's grandfather. The little boy is Queen Elizabeth's great-grandchild.

They posted a stop motion video including images of Kate being walked down the aisle by her father.

In yet another Instagram story the queen's granddaughter shared, fans are excited to hear the cooing of baby August as he played with a stuffed shark in his little rocker. He has a head full of brownish-red hair like his parents do.

The Instagram story was followed by a series of pictures commemorating World's Oceans Day, a day to celebrate the magnificent oceans and all creatures it harbors. Her caption read:

"Today we were celebrating goal 14: Life Below Water on World Oceans Day." ⁣

Princess Eugenie is not the only royal that celebrated fathers day this year. The Royal Family, on their official page, released beautiful photos on social media, celebrating the day and in remembrance of those they’ve lost.

One photo posted on the family’s page shows the queen as a young woman with her dad, King George V1, and her late husband, Phillip, as they watched little Prince Charles playing.

Prince Charles and the Duchess of Cornwall posted four photos, one of Charles with his sons, Harry and William, two more showed Camilla with her father, who passed on in 2006, and a fourth of Prince Charles as a young boy.

Prince William and his wife Kate Middleton were not left behind in the celebration. They posted a stop motion video including images of Kate being walked down the aisle by her father, Michael Middleton, among other photos. It spelled out the words “Happy Fathers Day.”
