Appearances can be deceiving when it comes to celebrities.
Not in Kate Middleton's case, however. She's the very best!
At least according to her uncle Gary Goldsmith, who tells Hello! that his niece is just as sweet, smart, and smitten with Prince William as she seems in public.
"She is so kind-hearted, a beautiful girl inside and out," IT recruitment millionaire Goldsmith said. "I think that is the Kate people are seeing and the Kate I know."
"She is this confident, clever, caring girl who takes responsibility seriously. I think everyone thinks she's sincere, in love, and doing her job to the best of her ability."
"She is incredibly grounded," he adds of Kate Middleton.
"Kate's going to make a brilliant mum... You couldn't want for a better kid than her, and that's going to shine through with her as a parent as well."
Goldsmith, the younger brother of Kate and Pippa Middleton's mother, Carole, also has kind words for his niece's husband, the Duke of Cambridge himself.
Recalling the first time he met Prince William at a family supper back in 2006, the Duchess' uncle says he knew he was seeing something special.
"When I saw them together, you actually thought, even if he wasn't going to be the King, they'd make a great couple," he says. "They were very, very good together."
"[William] was so relaxed in his own skin, but he does try very hard to be a real gentleman. He leaves an impact on you. He was incredibly charming and engaging."
"You know as a couple they will make it work as best they can."
Somehow we're not surprised. They do seem pretty great.
