Prince William has "the best bits" of both of his parents.
The royal's grandmother Queen Elizabeth is proud of the man he has grown up to be and sees both his mother Princess Diana and his father Prince Charles in him.
A source told the Daily Mail: "The Queen sees in him the best bits of Diana but also of Charles."
And William, 31, also reminds the Queen of her own husband, Prince Philip.
The insider explained: "In William, she sees so much of what Philip was - headstrong, certainly, and on the snappy side, with a short fuse, but fundamentally a young man who needs his independence for as long as possible - just like Prince Philip.
"At certain times, William, with his broad shoulders and the way he holds himself, even looks like his grandfather.
"And when she sees flashes of Philip, too, it makes her feel very confident about the future."
While William has recently been blasted for his small number of royal duties, the Queen has actually sanctioned his smaller role in order to ensure he and his wife Duchess Catherine "have as they need to be close to their children while they are small".
The monarch wants to make sure that William and Catherine's children Prince George, two and Princess Charlotte, 10 months, are settled before William increases his royal duties.
