Dwayne Johnson and Kevin Hart's on-set shenanigans are fast becoming the best part of the their films.

They first started roasting each other while working on Central Intelligence, but now they're taking digs at each other in the jungle - on the set of Jumanji.

Johnson posted the above video to Instagram earlier this weekend, in which Hart puffs out his chest and mocks Johnson, makes fun of him for driving around set rather than walking.

Johnson is pretty proactive on social media and has shared lots of videos and pictures from the set already, most recently using Instagram to share a first look at Jonas' character in the upcoming film.

"Officially welcoming my guy @Nick Jonas to #Jumanji. Great dude, great positive energy and very talented. He's gonna kill this role like I kill things with my bare hands.

"The jungle awaits. The adventure continues. And ironically the one who sings the most on set is Jack Black. #OnLocation #Hawaii #WelcomeToTheFamilyNick #Jumanji," Johnson wrote.

It's still up in the air about who Nick Jonas is playing but he seems pretty excited about it.

Jonas also posted on Instagram:

"DJ and I looking tough. JUMANJI It's going down... This cast, crew and creative team are incredible. So pumped to be alongside @therock @kevinhart4real @jackblack @karengillanofficial in this epic adventure. The journey continues. #hawaii #jumanji."

Oh hey there... @jackblack #jumanji

Kiwi comedian Rhys Darby is also joining the cast of Sony's Jumanji.

The movie is the continuation of the original and other cast members are Kevin Hart, Jack Black and Karen Gillan. The film is based on the screen adaptation of Chris Van Allsburg's book, which featured Robin Williams and grossed $260 million globally.

Welcome to summer goofballs!
