Prince William used to have a sweet tooth, and it is unclear if he still has it now.

The adorable young royal was previously photographed opening an ice cream cone while hanging out with Princess Diana. In the unearthed photo, the Duke of Cambridge is wearing a striped long-sleeved polo shirt and his cheeks look very plump and rosy.

His small hands are trying to unwrap the ice cream cone while he’s sitting beside his late mom. Princess Diana, on the other hand, is wearing a sleeveless polka dot dress. She is holding a plastic cup of soda, and she also has a smirk on her face.

Prince William and Princess Diana used to hang out a lot when the latter was still alive. In fact, the latter made sure to raise her two sons as normal as possible. For instance, Princess Diana made it a point to take Prince William and Prince Harry to McDonald’s.

While speaking with Marie Claire, Princess Diana’s former royal chef, Darren McGrady, said that the Princess of Wales regularly took her sons to the fast-food chain for one simple reason.

“I remember the Princess came into the kitchen one day and said, ‘Cancel lunch for the boys I'm taking them out, we’re going to McDonald's.’ And I said, ‘Oh my god your royal highness, I can do that, I can do burgers,’” McGrady said.

Princess Diana then told the royal chef that her boys want to avail of the Happy Meal toys. “Yeah, the boys loved McDonald's, and going out to pizza, and having potato skins—sort of the American foods. They were royal princes but had children's palates,” McGrady said.

The Princess of Wales’ former royal butler, Paul Burrell, echoed McGrady’s statement. He said that the trip of McDonald’s took place almost every Saturday night.

“The three of them would nip to McDonald’s for a Big Mac and fries before coming back to watch ‘Blind Date.’ All three of them would squat on this massive, stuffed hippopotamus Diana had in her sitting room,” Burrell said.
