The Hollywood premiere of “Jackass: Best and Last” is quickly approaching … and TMZ has learned a surprising invite went out.

Sources tell TMZ … Bam Margera got a ticket to the big event for the final ‘Jackass’ film dropping next month … but he’s unable to make it because he’s got a prior engagement.

We’re also told that he’s not quite ready for a reunion after a bitter fallout with the cast, specifically Johnny Knoxville and director Jeff Tremaine … but he’s for sure rooting for the flick to be a giant success, like all the others have been.

Bam might not be at the premiere … but we’re told he’ll have some reps there of sorts — his parents, Phil and April — who are fan favorites from the franchise.

TMZ broke the story … Bam made a deal earlier this year that allowed producers to use old, never-before-seen footage of him in ‘Best and Last,’ which will be a mix of newly shot stunts and unseen OG footage.

As you know … Bam has a super bitter fallout with the ‘Jackass’ fam and Paramount after he was fired from the last film for allegedly breaking his contract, which included a stipulation that he had to stay sober.

Bam later sued Paramount, Knoxville and Tremaine over wrongful termination in 2022 and settled.
