As we edge ever closer the 20th anniversary of Princess Diana’s death at the end of August, coverage and commentary around the late royal has skyrocketed. We’ve heard devastating details about her funeral, learned about the breakdown of her marriage, and emptied more than one box of tissues over the personal stories shared by her sons, Prince William and Prince Harry. And now, amongst the sadness of a life taken too soon, a very cheeky story has emerged from the pack.

According to Darren McGrady, Diana’s former head chef, the beloved royal once ordered a cake made to resemble a pair of breasts for William’s 13th birthday. She also invited Claudia Schiffer, Christy Turlington, and Naomi Campbell — you know, the world’s most famous supermodels — over for the special occasion.

“I remember that day really well because the Princess said they were coming,” McGrady recently told Hello! magazine. “I was super excited and I wanted to meet them too but I didn’t get the chance. It was Claudia Schiffer, Christy Turlington, and Naomi Campbell.”

Darren — who will soon release his second cookbook The Royal Chef at Home — recalled the cheeky surprise in hilarious detail. “I came into work that morning and went down to the refrigerator, opened the door, and I was just confronted with the biggest pair of boobs I’ve ever seen in my life,” he said. “The Princess had ordered a boobs cake for William’s 13th birthday. I wish I’d taken a photograph of it! I didn’t know anything about it, I just thought, ‘Oh my gosh.’ I asked the butler, ‘What on earth is this?’ and he said the Princess had ordered it for William’s birthday.”

“The Princess loved embarrassing people in the nicest way, in a fun way, whether it was telling a dirty, risqué joke — which usually got me. William just went bright-red,” McGrady added. William was just 15 and his brother, Harry, only 12, when their beloved mother died at age 36 from injuries sustained in a car crash in Paris on Aug. 31, 1997. The royal siblings will soon speak publicly — and in depth — about the days that followed the death of their beloved mother in BBC1’s new documentary, Diana, 7 Days.

In a teaser for the 90-minute documentary, William explains he and his younger brother felt compelled to “stand up” and protect their mother by sharing their words — something they weren’t able to do at the time of her tragic passing. “Part of the reason why Harry and I want to do this is because we feel we owe it to her,” William said. “I think an element of it is feeling like we let her down when we were younger. We couldn’t protect her. We feel we at least owe her 20 years on to stand up for her name and remind everybody of the character and person that she was.”

The film will also feature a selection of interviews with those who were at the “eye of the storm” in the days following Princess Diana’s death — including, among others, her brother Earl Spencer, her sister Lady Sarah McCorquodale, and the Princess’ lady-in-waiting Anne Beckwith-Smith.
