Her grandchild Prince William is among those honoring the record-breaking monarch in ITV’s documentary The Queen at Ninety, which will air on March 27 in the U.K.

The Duke of Cambridge, 33, opened up about how the Queen helped shape his personality as an adult.

“Growing up, having this figurehead, having this stability above me has been incredible,” the Duchess of Cambridge’s husband says. “I have been able to explore, understand, slightly carve my own path. I greatly appreciate and value that protection.”

Prince George and Princess Charlotte’s father also talked about how the public reacts when meeting his grandmother.

“A lot of people get very excited and sort of nervous around her. And I’ve seen some very comical moments. I’ve seen people literally faint in front of her. It’s quite a startling moment as to what to do when you faint in front of the Queen,” William says.

“There’s a lot of trembling knees and people can’t talk sometimes. It’s quite difficult talking to people when they can’t talk. You don’t get very far; I don’t get past the hellos,” he adds.

The Duchess of Cambridge, née Kate Middleton, also talked about the Queen’s relationship with her grandson, Prince George, in the documentary.

“George is only two-and-a-half and he calls her ‘Gan-Gan,’ ” Catherine says. “She always leaves a little gift or something in their room when we go and stay and that just shows her love for her family.”

Besides William and Kate, Prince Harry, Prince Charles, the Duchess of Cornwall, Princesses Beatrice and Eugenie were also among those featured in the documentary.
