The Duchess of Cambridge painted the town red as she dazzled the West End for a musical opening night.
Kate shone in a maroon Marchesa gown on the red carpet for Broadway classic 42nd Street.
She was the star guest at the glittering production, raising moneyfor a children's hospice.
And Ollie Duell,12, a patient at East Anglia Children's Hospice (EACH), presented Kate with a programme.
Starstruck Ollie, who has complex, undiagnosed stomach problems, said: "I feel very good about meeting Kate Middleton.
"She's very pretty and I want to talk to her about the hospice and how I like going there.
"I also want to tell her about Pokemon."
Caring Kate bent down to chat to the lad, from Cambridge, as flash guns lit up the red carpet last night.
Other stars included Hollywood legend Morgan Freeman.
Each has been allowed to include an advert calling for donations in the show's programme.
The charity has already received a £250,000 donation as a result of the partnership.
The Broadway revival - at the Theatre Royal Drury Lane - is helping raise money for a new purpose built hospice in Norfolk called The Nook.
The Duchess - who became a Patron of the charity in 2012 - smiled broadly as the show kicked off with a rousing tap dance routine.
Co producer Lord Grade said: "The Duchess expressed an interest in coming which is fantastic.
"It adds to the sense of occasion."
