TMZ.COM is reporting that The Rock’s Instagram post where he unleashed on un-named male co-stars from the Fast & Furious franchise was directed at none other than Vin Diesel.

The two Hollywood stars had additional scenes to film yesterday and according to sources on set, Diesel went to The Rock’s trailer to confront him about the comments. The two took their time privately to discuss but TMZ adds that whatever bad blood there is between the two was not resolved. “One source intimately familiar with the actors tells us it’s all about big egos,” TMZ wrote.

Both Diesel and Rock finished up their scenes together at around 1AM this morning and Diesel then left for good as his scenes for the 8th installment are done. Johnson wraps up his part, playing the character of Luke Hobbs, tomorrow.
