The Hunger Games beauty, 26, was given the opportunity to get her own back on the cheeky actor, 37, when she appeared on Jimmy Kimmel Live! on Monday, December 12.
After the host showed her the pile of hilarious pictures Pratt had created, Lawrence decided it was time to fight back.
Faking rage, Lawrence stormed out of the studio, with a spray can in hand, and waved down a sightseeing bus on Hollywood Boulevard, that just so happened to have an ad for their new movie on the side of it.
She wasted no time spraying over Pratt’s eyes and mouth, giving him a monobrow and beard too.
Kimmel got in on the action as well by crossing out some of the letters in the movie title to spell out "Ass."
The pair topped it off by giving him red devil eyes and a matching goatee.
Lawrence and Pratt have been busy pulling off pranks and stunts to promote their new flick.
They played a hilarious game of BBC One’s Playground Insults during their London promo tour.
Watch the clip above to see Lawrence defacing Pratt, and also check out the funny video of her chat with Kimmel where they bond over being hypochondriacs.
