So who actually are they? Well let's start with Jasper Dolphin from the Loiter Squad which is a sketch-comedy series starring Tyler, The Creator, Taco Bennett, Jasper and Lionel Boyce.
The show has featured guest stars from the Jackass franchise including Johnny Knoxville, Bam Margera and Dave England.
Next up is Poopies - otherwise known as Sean McInerney - who is described by Steve-O as 'royalty in the world of surfing'.
Luckily, it seems Poopies has an innate willingness to hurt himself for others' entertainment which is lucky considering the vibe.
The YouTuber has previously hinted that he was going to be in a film with Johnny Knoxville when he was asked by The Inertia whether he's a movie star and replied: "Soon to be, you'll see the movie. I can't tell you what it is right now, but you'll see it soon."
When quizzed about whether Knoxville would be making an appearance, he added: "It has to do something with him."
Last but by no means least is Zach Holmes who is described as Steve-O's 'favourite new guy'.
The clip Steve-O released shows a snippet of Zach (Zackass) on the show - well, we hope that's what it is and he doesn't strap explosives to his body for the fun of it.
Steve-O revealed the new cast members as he shared a vlog of his adventures with his nephew Dylan. Oh and he referred to himself as a 'funcle' which is a fun uncle. Might be the most uncool thing he's ever said tbh.
He took Dyllan to the set of the upcoming movie where he ran into Eric André, Johnny Knoxville, Chris Pontius, Wee Man, Preston Lacy, Spike Jonze and Jeff Tremaine.
It'll be the first time the gang have filmed together since the 2010 Jackass 3D movie.
"I feel like I've been extremely lucky to take the chances I've taken and still be walking around."
The film is set to be released on 22 October 2021.
