We now know who Dwayne “The Rock” Johnson was referring to when he blasted a Fast & Furious 8 co-star on Instagram earlier this week.

Word is, he was calling out none other than Vin Diesel, according to TMZ Tuesday.

Apparently the two have been going head-to-head so much that they had to have a secret meeting in hopes of settling their differences earlier that day. Their feud is said to have sparked after Vin, who also works as a producer on the film, made calls that Johnson wasn’t too fond of. Things got so bad that it was becoming more and more difficult for the two to film key scenes together, the site added. It’s not clear if they were able to come to a consensus during their meeting. But now Johnson has ruffled the feathers of his other co-stars after his rant on social media.

Check out his message that is said to be about Vin below.

  While the entertainment news site confirmed that it was Vin Diesel, many fans assumed that Johnson was referring to his other co-star Tyrese. But Tyrese shared a lengthy message on his own Instagram that shut down that theory.

He first said that no one is clear why The Rock decided to go off on Instagram, but added that he should have called out whoever he had a problem with by name. He also went on to make it clear he will not let anyone shut down the franchise; especially after the passing of his “brother” and co-star Paul Walker. He has since deleted it but check out his full post below courtesy of Baller Alert.
