The Rock trashed co-stars who aren't "stand up men," and we might know who he's talking about

Some serious heat between these two.

Dwayne "The Rock" Johnson sent social media abuzz after posting an Instagram where he called out some male co-stars, who aren't conducting themselves as "stand up men."

TMZ has since reported that rant was directed at Vin Diesel:

"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.

According to the report, the cast isn't thrilled with Rock sharing this business and it's unknown if their issues were resolved.

Does this mean we might get a Wrestlemania throwdown between The Rock and Diesel? Don't bet on it.
