The usually unflappable Kate Middleton has proved she's just like the rest of us really - after hilarious footage emerged of her rolling her eyes when told to "keep wrapping" at a children's charity event in New York.
The incident occurred during a visit to the Northside Centre for Child Development in the deprived Harlem district of New York.
The duchess joined in wrapping presents that would reach some of the city's poorest children for Christmas.
But as she's happily doing so, a well-wisher taps her on the shoulder and says "keep wrapping". A seemingly irritated Kate looks away and rolls her eyes in apparent incredulity before continuing with the task at hand.
The 'side eye sass' was caught on camera and has now gone viral after being shown on America's Today Show.
Apart from obviously taking umbrage to the slightly bossy New Yorker, Kate appeared to enjoy her time at the centre, and wrapped with good grace.
According to the Daily Mail, Mary Dawkins, 71, a grandmother of six from Harlem, wrapped along with Kate.
She said, "We sat together wrapping gifts - she's my girl. She said she has to wrap gifts when she gets home."
Awww. Wonder what the Royal Santa is bringing little Prince George this year.
