Will Sage Astor-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 Will Sage AstorJune 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.

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."

"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."
