The Queen and Prince Philip keep a very close eye on the Duchess of Cambridge to make sure her royal life is running smoothly, a royal expert has claimed.
Kate joined the Firm back in 2011 when she married Prince William at Westminster Abbey, and has grown in confidence and popularity over the years.
But Tom Quinn claims the Monarch and her husband still want to make sure things are in order to avoid a repeat of her young royals before her.
Speaking on Channel 5's documentary William & Kate: Too Good To Be True, he said: "The Queen and the Duke of Edinburgh, will be watching very carefully, especially given that younger royals in the past have got things very badly wrong and they don't want that to happen again."
Kate has spoken honestly about being new to the royal role, and in her engagement interview said she was nervous about taking on the unique job.
She said: "It's nerve-racking because I don't know the ropes really, William is obviously used to it.
"I'm willing to learn quickly and work hard."
Supportive Wills added: "She'll do really well."
But experts praise Kate's approach to her new royal life and believe she is growing into the perfect Queen Consort.
Professor Suzannah Lipscomb told the programme: "What we're really seeing is just a blossoming of who she really is.
"She may not have been born to this role, she may not have been born to be Queen, but she's a hell of a classy lady.
"Class doesn't come from one's social status, it comes from one's upbringing and it comes from one's character. She has that in spades."Kate Middleton, Duchess of Cambridge Queen had 'grave concern' about Kate Kate before she was royal How Kate celebrates her birthdays Kate could get new title when Queen dies
Royal biographer Anna Pasternak also praises Kate for the way she's managed to change people's opinion on her in the past decade.
"Kate has absolutely managed to change the narrative about her, brilliantly so.
"She's moved from being Waity Katie, who was seen as rather lightweight doing nothing with her life, waiting for her prince to propose, to the Kate we see today who is absolutely embodies her royal role."
