Star of The Big Bang Theory Kaley Cuoco has shared some snaps of her transformation into a monkey for an upcoming episode of the hit comedy.

During the current season of the show, which is airing on RTÉ Two, Cuoco's character Penny was offered a part in a movie entitled Serial Ape-ist 2: Monkey See, Monkey Kill and although she turned it down originally, judging by these snaps it looks like Penny is set to change her mind.
