Today is Prince George's 10th birthday - happy birthday to the future king - and in addition to baking a cake for George late last night (the Princess of Wales customarily bakes cakes for her children's birthdays), Kate and Prince William have a new portrait of the heir to the throne for the milestone birthday Published.

According to People, the pictures were taken in Windsor earlier this month by Wales' new favorite photographer, Millie Pilkington. In the new image, George, looking more grown up than ever, smiles for the camera as he sits on the steps wearing a button-down shirt and long pants. The photo is reminiscent of a series of photos taken in November 2014. The future king, who was one year old at the time, posed on another staircase at Kensington Palace in London for a portrait that was released prior to the Christmas vacations that year.

In contrast to Kate, who took portraits of not only George but also his younger siblings Princess Charlotte and Prince Louis each year, the Welsh family used Pilkington's services frequently last year, including not only George's birthday portraits but also those of Charlotte and Louis The family has also been using Pilkington's services for a number of other projects. Pilkington also took their annual Father's Day portraits, with William posing with the trio in Windsor.

Prince Charles and Queen Camilla paid tribute to 10-year-old Prince George on social media, writing "Happy birthday, Prince George" along with a birthday cake emoji.

We appeared with the whole family at the Royal International Air Tattoo last week, and a few days later with my parents and Charlotte at the Wimbledon men's singles final. (According to the Daily Express, George's birthday party in Windsor will be soccer-themed, but not lavish.

"This birthday party is going to be a gathering of family, as well as close friends, friends from George's previous school, and friends from George's new school, but it's not going to be fancy," royal expert Katie Nichol told "Entertainment Tonight" Entertainment Tonight. A lavish party with huge expenses is not William and Kate's style."

Birthdays are important to William and Kate, Nicole said, and the couple is "known for celebrating big birthdays but doing it under the radar. So no matter what happens, they will stay firmly behind closed doors."

She continued, "(Kate) still bakes cakes all the time and will be having a tea party, and I hear there will be some kind of soccer-themed celebration."

George was born on July 22, 2013 at 4:24 p.m. at St. Mary's Hospital in London at 8 pounds 6 ounces. Kate recalled the moment she held her first child in her arms on the podcast Happy Mum, Happy Baby: "Amazing, amazing. Amazing, amazing. How can the human body do that? And he was so sweet. And I felt a certain relief that he was a happy, healthy boy."

The next day, William and Kate introduced their son, whose name has not yet been released, to the waiting crowd on the steps of the Lindo Wing at St. Mary's. She went on to say that "everyone was very supportive" and that she and William understood the importance of sharing their son with the public. She continued, "But just the same, there were a lot of mixed emotions with a newborn baby, inexperienced parents, and the anxiety of not knowing what to expect. "

Commenting on George's new birthday photo, body language expert Judy James told the Daily Express, "George seems to have taken a sudden, powerful step out of childhood with this stunning birthday photo. Gone is his cheeky grin and his more playful, childlike body language, and in its place is a relaxed, confident-looking young man in a pose reminiscent of his father."

James said his pose in the snap looks natural. 'George shows an even gaze here and a symmetrical, relaxed, natural smile. His pose on the stairs may have been awkward, but his long limbs make it look natural and genuine." He appears to be looking at the world in a calm and relaxed state, and here he looks very smart for his age. There is not an ounce of awkwardness in his posing for this portrait, just a sense of humor and a desire to appear as natural and unpretentious as possible."
