Vin Diesel left the 'Fast 8' set just minutes after his final scene wrapped on Wednesday.

During his speech Vin, who is said to regard himself as the franchise's father figure, said: "Daddy's gone".

While Vin and The Rock held private showdown talks over the former WWE star's social media tirade, the gossip site claims they were not able to resolve their differences.

Meanwhile, an insider claims the two actors have repeatedly "butted heads" throughout filming after the 44-year-old actor - whose own filming wraps on Thursday "lost patience" with his co-star's "difficult" behaviour.

A source told the New York Post newspaper's Page Six column: "Vin Diesel and the Dwayne Johnson have been butting heads throughout the production of 'Fast 8'.

"Vin has a reputation for being difficult -- he shows up late, keeps people waiting, holds up production and is disrespectful to people on the set. Dwayne lost his patience with him."

However, other sources told the website it was The Rock who was frequently late, much to his co-star's annoyance.

The 'Baywatch' actor hasn't directly addressed the situation since making his cryptic post earlier this week, but he has now taken to Instagram to praise the importance of "team effort" while also insisting conflict can be a "good thing".

He posted on Instagram: "You guys reading this know how much I believe in the idea of team effort. That means respecting every person, their time and their value when they step onto my set or partner with our production company. And like with any team, that's a family, there's gonna be conflict. Family is gonna have differences of opinion and fundamental core beliefs. To me, conflict can be a good thing, when it's followed by great resolution. I was raised on healthy conflict and welcome it. And like any family, we get better from it."

In his original rant, the wrestling champion praised his female co-stars in the film, Charlize Theron, Jordana Brewster and Michelle Rodriguez, but admitted it was a "different story" working with the guys.

Dwayne - who plays bounty hunter Luke Hobbs - wrote on Facebook: "This is my final week of shooting Fast & Furious 8. There's no other franchise that gets my blood boiling more than this one.

"An incredible hard working crew. Universal Studios Entertainment has been great partners as well. My female co-stars are always amazing and I love 'em. My male co-stars however are a different story.

"Some conduct themselves as stand up men and true professionals, while others don't. The ones that don't are too chicken s**t to do anything about it anyway. Candy asses.(sic)"

He also stars alongside Scott Eastwood, Jason Statham, Tyrese Gibson, Kurt Russell and Ludacris in the next installment of the action franchise.
