Apparently, The Rock's explosive Instagram rant about his male Fast 8 castmembers had one specific target: Vin Diesel. This, at least, is according to TMZ, who says that the entire cast is miffed at The Rock because of his Instagram post.

The gossip site says:

We're told The Rock has butted heads with Vin during the production, in part because V.D. is a producer and has made decisions that didn't sit well with the former wrestling champ.

Our sources say The Rock and Vin had a meeting on the Atlanta set mid-day Tuesday ... partly because tensions were running so high it was almost impossible to shoot scenes. We do not know if they resolved their issues.
