"So today is XXX Thursdays and I'm actually going to see the first cut of XXX," Diesel shared in an Instagram video on Thursday, captioned "All love."
The 49-year-old star continued to talk about his excitement over the film, before making us squirm with this line: "I wanted to share something with you…"
However, after a long pause, it was a sweet story about Paul Walker that the actor shared. "My son earlier this morning, we were going over his birthday list, and he said, 'I want Paul to come. I really miss him,'" he explained. "Paul came to his second birthday in London when we were shooting Fast 6."
Diesel then opted for a Facebook Live session in which we were sure he would offer insight into his feud with Johnson.
"A little anxious, excited and anxious…" the Riddick star teased, before again discussing XXX.
Diesel spoke at length about possible sequels, the film's hardworking crew, and his excitement over the screening before taking a long pause. "And I will tell you everything," he said, repeating his cryptic line from the day before. "Once I see the movie, I'll come back and tell you everything."
While the father of three's Facebook Live session lasted for 7 minutes, it seems he just couldn't find time to discuss Johnson between talking about XXX, speaking French, and then talking more about XXX.
Though Diesel seems unconcerned about the reported Fast 8 feud, a source tells ET it was in fact the actor that Johnson had a problem with.
"There were several times Vin was late to set and it really started pissing Dwayne and the other cast and crew off," the source says. "Dwayne was always on time for shooting. It was Vin who would often show up when he felt like showing up. Dwayne is the complete opposite."
"At the end of production Dwayne was really over Vin's bulls**t," the source added, referring to Johnson's recent Instagram post which called out unnamed "chicken s**t" and "candy a**" co-stars for not acting like "true professionals."
While Diesel seems to be ignoring the feud, Johnson took to Instagram on Wednesday to further clarify his beef, attributing his outburst to a "difference of opinion."
"You guys reading this know how much I believe in the idea of a TEAM EFFORT," he wrote on Instagram. "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."
"Conflict can be a good thing, when it's followed by great resolution," he added.
While many of Johnson and Diesel's Fast 8 co-stars have stayed silent, Tyrese Gibson has spoken out -- but it seems the actor can't decide who to support.
Gibson first seemed to support Johnson, responding to his rant with an Instagram of his own in which he called the former wrestler his "brother."
"DJ happens to be one of the most humble, down to earth and professional people I've ever worked with," he said in the now-deleted post.
Gibson appears to have since switched sides, adding several photos with Diesel to his account, and referring to the Guardians of the Galaxy star as his "brother for life."
"Our brotherhood and every moment has inspired me to be a better man and father," he wrote on Thursday. "I'm so f**king proud to call you my family and my brother."
"I've always said that if ONLY people knew how hard you work to protect this franchise and characters, minds would be blown," he continued. "You're my brother for life let's keep it positive and keep rockin this thing."
