The Rock accused Diesel of using both his children and their co-star Paul Walker's death in order to "manipulate" the situation and guilt him into returning to the franchise, despite many private and public conversations Johnson claims the two have had.
Last month, Diesel posted a photo of the two actors from an F&F scene. He wrote a lengthy caption, pleading for The Rock to "show up" to film the franchise's finale.
Vin began the post by calling the former wrestler his "little brother Dwayne" and telling him that "the time has come."
"The world awaits the finale of Fast 10," the 54-year-old actor explained. "As you know, my children refer to you as Uncle Dwayne in my house. There is not a holiday that goes by that they and you don't send well wishes...but the time has come. Legacy awaits. I told you years ago that I was going to fulfill my promise to Pablo. I swore that we would reach and manifest the best Fast in the finale that is 10! I say this out of love..."
Vin once again reminded the 49-year-old entertainer in his message that he "must show up, do not leave the franchise idle you have a very important role to play. Hobbs can't be played by no other."
He concluded the loaded note by saying, "I hope that you rise to the occasion and fulfill your destiny."
Not only did Diesel's post catch Johnson off guard, but it also really upset him.
Speaking to CNN, the latter said he "was very surprised" by the public plea.
"This past June, when Vin and I actually connected not over social media, I told him directly - and privately - that I would not be returning to the franchise," Dwayne explained when asked about the drama. "I was firm yet cordial with my words and said that I would always be supportive of the cast and always root for the franchise to be successful, but that there was no chance I would return."
Johnson went so far as to call Diesel's message "an example of his manipulation," pointing to the fact that he "didn't like that he brought up his children in the post, as well as Paul Walker's death."
The ex-WWE star said Vin should "leave them out of it" and once again claimed they "had spoken months ago about this and came to a clear understanding."
This isn't the first time The Rock has alluded to issues with Vin. In 2016, while filming the eighth installment of the franchise, he revealed that he was not a fan of his male cast members.
"There's no other franchise that gets my blood boiling more than this one," he confessed at the time. "My female costars are always amazing, and I love 'em. My male costars, however, are a different story."
