According to new reports from TMZ, the target of his wrath was co-star Vin Diesel. The former wrestler is believed to have taken aim at his fellow action star because the pair reportedly clashed several times during filming of the upcoming eighth movie after falling out over decisions made by Vin in his extra role as producer.
The website also revealed the pair met for crisis talks on the set of the film in Atlanta yesterday in a bid to bury the hatchet after Dwayne shared the post below on Instagram alongside a video of a fight scene from the movie.
It is not yet known if the talks were successful and if they pair managed to put the feud behind them.
Other male stars in the movie include Scott Eastwood and Jason Statham.
Fast 8 is set to be released in UK cinemas on 14 April 2017.
