What’s going on between Vin Diesel and Dwayne “The Rock” Johnson?

According to TMZ, the co-stars were embroiled in some sort of beef on the set of “Fast 8.” At this time, Diesel hasn’t spoken out about his issues with Johnson, but he reportedly stormed off the “Furious” set as soon as he wrapped his scenes early Wednesday morning.

TMZ sources stated that Diesel didn’t like a particular Instagram post the semi-retired wrestler shared, and that’s when things got heated.

“This is my final week of shooting #FastAndFurious8,” Johnson wrote on the social site Tuesday. “An incredible hard-working crew. Universal 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,” he continued. “The ones that don’t are too chicken s--- to do anything about it anyway. Candy a----. When you watch this movie next April, and it seems like I’m not acting in some of these scenes, and my blood is legit boiling, you’re right.”

After the now-deleted message surfaced — which a portion of was published by the Daily Mail — Diesel reportedly went to Johnson’s trailer to question him about it, and although they spoke, their issues weren’t resolved. Then on Wednesday, “Furious 8” co-star Tyrese Gibson commented on Johnson’s message after some believed he was the person mentioned by the actor in his post.

“Why are you guys so impressionable?" wrote Gibson in a now-deleted post, which included a video of Johnson singing to his daughter. “A man wouldn’t be singing from his heart and soul to another man’s little angel if he had a problem with her dad.”

Upon checking Diesel’s Instagram and Twitter, he hasn’t mentioned anything about the alleged spat, and there’s a good chance that he wants to keep the details of everything under wraps.

From here, it’ll be interesting to see how the two stars get along during the promotion of the film, because unless they settle things, it could be a very awkward time for them both.
