Prince William has shared intimate details of his family life in a new documentary for the Queen's Birthday.
Queen Elizabeth II is turning 90 today, a milestone celebrated across the Commonwealth. However, the most touching tribute came from where it matters most - within her own family.
Prince William, appearing on a documentary, The Queen at 90, revealed how he looked up to his grandmother after his mother passed away.
"She's been a very strong female influence," he said.
"Having lost my mother at a young age, it's been particularly important to me that I've had somebody like the Queen to look up to and who's been there and who has understood some of the more, um, complex issues when you lose a loved one.
"So she's been incredibly supportive and I've really appreciated her guidance."
William's mother, Princess Diana, died in a car crash in 1997 when he was just 15 years old.
In the interview, he also discussed fond memories of his childhood and how the Queen is supportive of William prioritising his family life when possible.
