Kate Middleton Celebrates Prince William's Birthday With New Family Photo

You'll want to jump at the opportunity to see Kate Middleton's new family photo.

To celebrate her husband Prince William turning 42 on June 21, the Princess of Wales shared a sweet snapshot she took of him with their kids Prince George, 10; Princess Charlotte, 9, and Prince Louis, 6.

Donning a casual navy sweatshirt over a pair of red shorts, the Prince of Wales could be seen holding hands with his children as they jumped in the air at the beach.

"Happy birthday Papa," Kate, a.k.a. Catherine, captioned the post, "we all love you so much! Cx." 

This isn't the only recent glimpse fans have gotten into the royal family's world. Last week, Kate marked Father's Day by sharing another photo she snapped of William at the beach with George, Charlotte and Louis. 

"We love you, Papa. Happy Father's Day," the June 16 Instagram post read, which was signed by the kids with their initials, "G, C & L."

And just the day before, the couple and their kids seen attending Trooping The Colour in London.

The celebration marked Kate's first official public appearance since she announced her cancer diagnosis in March—with the princess confirming her Trooping The Colour attendance and giving an update on her health days before the event. 

"I am making good progress, but as anyone going through chemotherapy will know, there are good days and bad days," she stated in a June 14 Instagram post. "On those bad days you feel weak, tired and you have to give in to your body resting. But on the good days, when you feel stronger, you want to make the most of feeling well."

Kate noted in the message that her "treatment is ongoing and will be for a few more months." And while she expressed her "hope to join a few public engagements over the summer," she acknowledged she isn't "out of the woods yet."

"I am learning how to be patient, especially with uncertainty," the 42-year-old added. "Taking each day as it comes, listening to my body, and allowing myself to take this much needed time to heal."

Back in April, William's father King Charles III returned to his public-facing duties after undergoing treatment for his cancer diagnosis, which was announced in February.

Nearly three months after sharing her cancer diagnosis, the Princess of Wales said that she's "making good progress" with chemotherapy, though there are "good days and bad days" amid her health journey.

"On those bad days you feel weak, tired and you have to give in to your body resting," Kate wrote on Instagram June 14. "But on the good days, when you feel stronger, you want to make the most of feeling well."

She added, "My treatment is ongoing and will be for a few more months. On the days I feel well enough, it is a joy to engage with school life, spend personal time on the things that give me energy and positivity, as well as starting to do a little work from home."

On May 13, King Charles III bestowed the title of Colonel-in-Chief of the Army Air Corps to his oldest son, sparking controversy as many royal watchers believed the title would be more suited for Prince Harry, who trained and served in the military branch.

In a March 22 video message, the Princess of Wales shared that she'd been diagnosed with cancer after undergoing abdominal surgery in January.

"It was thought that my condition was non-cancerous. The surgery was successful," she said before noting that tests after the operation found cancer had been present. "My medical team therefore advised that I should undergo a course of preventative chemotherapy and I am now in the early stages of that treatment."

After photo agencies pulled the picture Kensington Palace shared of Kate since having her abdominal surgery on March 10, the Princess of Wales addressed claims the photo was doctored. 

"Like many amateur photographers, I do occasionally experiment with editing," she tweeted on March 11. "I wanted to express my apologies for any confusion the family photograph we shared yesterday caused. I hope everyone celebrating had a very happy Mother's Day. C."

Princess Diana's niece celebrated Mother's Day in the U.K. by sharing she and her husband Michael Lewis privately welcomed their first baby.

"Throughout this period, His Majesty will continue to undertake State business and official paperwork as usual.The King is grateful to his medical team for their swift intervention, which was made possible thanks to his recent hospital procedure. He remains wholly positive about his treatment and looks forward to returning to full public duty as soon as possible."

Shortly after Kate's hospitalization was made public, Buckingham Palace shared that Charles "has sought treatment for an enlarged prostate."

"His Majesty's condition is benign and he will attend hospital next week for a corrective procedure," the statement added. "The King’s public engagements will be postponed for a short period of recuperation."
