As if we weren't already excited enough for the unveiling of One Direction's new video for Steal My Girltomorrow, the boys have gone and shared these cheeky pics of them playing with a monkey on set.

Louis Tomlinson and Zayn Malik can be seen hanging out with the unofficial sixth member of the band, an incredibly cute chimp, as they tickle his belly in a ridiculously adorable way.

We've already seen Zayn bump chests with a couple of sumo wrestlers, Liam join a marching band and a cameo appearance from Hollywood royalty Danny DeVito, making it simply impossible to predict what will come next!

Steal My Girl is taken from 1D's forthcoming new album Four, and will be unveiled in all it's anticipated glory tomorrow (October 24).
