Camilla appeared captivated by the 'In conversation' event, which saw Malorie Blackman discuss the theatre's current adaptation of her 1997 book Pig Heart Boy.
The queen, who has been a patron of the Unicorn Theatre since 2005, wore her blond hair in a classic blow dry and kept her make-up simple for the daytime event, adding a slick of lipstick and some dark eyeliner.
