Kate Middleton was the picture of perfection as she traipsed through Canada this past week like a royal pro with her new hubby, William.
But while Kate has proved she can get her hands dirty and still look damn good while doing it, what do the royal insiders think of her North American tour performance so far?
"I don't think she has it quite down yet," explains a palace source who's been watching the Duchess of Cambridge's every public (and private) move. "There was a point on their first day together, while inspecting the troops with the British governor general at Rideau Hall, Kate was actually giggling."
A major no-no.
"She actually giggled [and] was talking to the governor general's wife behind her hand, they were obviously having quite the conversation," dishes our insider. "Now, had this been Fergie, she would have been kicked hard for doing it, but, I think people are being very kind—right now."
Lucky for Kate, the palace heartily approves of Prince William's choice of bride, and considering this is her first royal tour and first time to North America ever, they are willing to give the gal a decent grace period. But not, say, forever.
So perhaps Kate should take a page out of her hubby's increasingly very prim and proper book?
"William is turning out to be much more like Charles than Diana," says our palace pal. "He's rather stiff, and he takes his duties incredibly seriously."
Well, almost as seriously as he takes his street hockey game, that is.
