Vin Diesel has told his Instagram followers he will reveal "everything" following Dwayne "The Rock" Johnson's recent criticism.
The Hollywood star is thought to be the focus of Dwayne's criticism about his unprofessional co-star on the set of Fast 8 earlier this week, but Vin has now taken to the photo-sharing website to address the situation.
He said, in reference to his 17-month-old daughter Pauline: "After being on set since literally Christmas and to finally come home and learn that your little angel learned a new word ... I have to share it with you, it's more important than anything.
"Her new word kind of describes my spirit and soul and most people who stay positive. The new word is 'happy'. When I heard her say happy I just lit up in ways that I can't describe."
Vin finished the cryptic video by saying: "Just give me a second and I will tell you everything. Everything."
The Instagram video was accompanied by a caption that read: "So much has gone on this year. I can't believe I wrapped two back to back pictures I both starred in and produced. Now I get to return to my family, my life ... To me."
Later, Vin took to the same site to heap praise on his Triple X movie, but failed to make any mention of the money-spinning Fast & Furious franchise.
He wrote: "Making Triple X was so rewarding on so many levels. You need a lot of heart to execute some of the action sequences we pulled off... But WE did it! So proud of the entire xXx team. Today I am seeing the first cut. Excited is an understatement. #xXxThursdays. (sic)"
Although Dwayne did not explicitly cite Vin as the source of his frustration while making the movie, the two stars are said to have fallen out during filming.
A source told the New York Post newspaper: "Vin Diesel and 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."
Production sources told TMZ that The Rock had been upset with Vin's work ethic for "a long time", with the actor frequently 30-60 minutes late to shoot scenes, despite already being on set, as he would refuse to leave his trailer.
And crew members claimed start time on Mondays was shifted to 10am to accommodate Vin as he didn't like to start the week with a 7am call.
The crew source also slammed the actor's "out of control arrogance", which was triggered by his producer title, and accused him of refusing to listen to anyone and goading castmates, including The Rock, by criticising their acting.
On the other hand, the insider praised The Rock as the "ultimate professional", who was easy to work with, always on time and always nailed his scenes.
The two men are believed to have had private showdown talks on Tuesday, but their issues remain unresolved and Vin is said to have left the set minutes after completing his final scenes on Wednesday.
In his original rant, former wrestler The Rock 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.
The actor - 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)"
