If you need to catch up on this whacky feud, here are a few articles that will get you up to speed. But now, thanks to TMZ, we're able to reveal the real reason the beef between these two heavyweights started in the first place.
According to TMZ, The Rock and Diesel were arguing about their "real estate" during the filming of their latest movie, The Fate of the Furious, meaning the amount of screen time an actor receives in a film. Two superstars arguing about who got the bigger role – who would've thought it?
The Rock was particularly angered at the decision to give him a slightly lesser role, but eventually conceded that the Fast franchise is what it is today heavily due to Diesel's influence.
But no doubt all the nasty words and aggression would've flown out the window after the movie's opening weekend; Fate of the Furious ended up breaking multiple box office records and is raking in truckloads of cash by the day.
Thankfully for all fans who enjoy watching The Rock and Diesel together on the big-screen, TMZ also reported that this won't be the last movie these two badasses do together, with The Rock being reportedly "100% in" for their next adventure.
