Royals share new photo of ‘Papa’ Prince William for his birthday taken by Kate Middleton

In honor of Prince William's 42nd birthday, Catherine, the Princess of Wales, shared an adorable photo of him with their three kids.

In the photo, William was seen jumping into the air alongside his three children: Prince George, Princess Charlotte and Prince Louis.

"Happy birthday Papa, we all love you so much! Cx" the post was captioned, with a sign-off from Kate.

The Prince and Princess of Wales previously posted another photo of William, George, Charlotte and Louis on a beach earlier this week to celebrate Father's Day.

The photo was taken from behind as William wrapped his arms around George and Charlotte. Louis stood in between William and George, not quite tall enough to reach the hug from his father, so his older brother wrapped his arm around him.

"We love you, Papa. Happy Father’s Day," the June 16 post read, along with a heart emoji.

The message included the three children's initials, "G, C & L," and the caption noted Kate also took the photo. Kensington Palace confirmed that this was the first time a message from the children was posted on the Prince and Princess of Wales’ social channels.

The pair of photos come after Kate made her first public appearance at Trooping the Colour, a British military ceremony celebrating the monarch's birthday, since she announced in March she was undergoing treatment for cancer.

Prior to the event, Kate released a statement giving an update on her cancer treatment, confirming she would attend the birthday celebration for King Charles III.

“I’m looking forward to attending The King’s Birthday Parade this weekend with my family and hope to join a few public engagements over the summer, but equally knowing I am not out of the woods yet,” she wrote.

“I am learning how to be patient, especially with uncertainty,” she continued. “Taking each day as it comes, listening to my body, and allowing myself to take this much needed time to heal.”

She added she had been "blown away" by the support she had received over the past few months.

“I am making good progress, but as anyone going through chemotherapy will know, there are good days and bad days,” she wrote. “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, George, Charlotte and Louis rode in a carriage down the Mall in London before they watched the king's birthday parade together on June 15, marking Kate's first public engagement since she revealed she was being treated for cancer.

The royal family then gathered together to stand on the balcony of Buckingham Palace to watch a flypast of military aircraft — this year, without as many adorable antics from Louis.
