ate Middleton and Prince William shocked onlookers in London on Thursday - after popping down to their local cinema to watch The Avengers.
Unwinding after the Diamond Jubilee celebrations, the royal couple did their best impression of regular folk by dressing down in jeans - with Wills even wearing a baseball cap and glasses.
K Middy rocked a pair of skinny jeans, a cropped jacket and swapped her trusty nude LK Bennet courts for a pair of simple black heels.
They kept their heads down and were almost unrecognisable as they joined the queue for the superhero blockbuster at the Odeon Kensington cinema.
But one excited fan definitely recognised the second in line to the throne and his wife, tweeting: "OMG watching the Avengers with Kate Middleton and Prince william sitting right next to me!!!!!"
Bet she wasn't paying much attention to the film then!
