The Rock has recently slammed his Fast 8 co-star Vin Diesel for being hard to work with and it looks like he has backup from some pretty reliable sources. The film's production crew has officially taken a side in the feud, and supports his claims that Diesel is a diva.

According to TMZ, production sources revealed that Diesel was 30 minutes to an hour late for shooting on multiple occasions, and it was not because he was late to set, but rather because he just didn't want to leave his trailer.

His diva antics allegedly spilled over into the morning calls as he reportedly wasn't a fan of the set Monday time of 7:00 a.m., so production was forced to change the start time to 10:00 a.m. to get him on board.

On top of that, Diesel reportedly was a pain on set in collaborating with the other actors, particularly The Rock. He allegedly would criticize his co-stars' acting performance while shooting and this made the crew uncomfortable, especially since he has a producer title on the film.

As far as The Rock is concerned, though, the crew loves him. They say he is a consummate professional and is always on time, nails his scenes and is a pleasure to work with.
