'Fast & Furious' Feud Revs Up: The Rock Snubs Vin Diesel

Earlier this month, Dwayne "The Rock" Johnson caught "Fast & Furious" fans offguard with an Instagram rant in which he dubbed one as-yet-unnamed male co-star a "candy ass."

Now, he's adding to speculation that Vin Diesel may have been the target of his disgust, thanking the entire cast and crew of "Fast 8" upon the film's completion — but leaving out Vin!

Us Magazine reports The Rock's warm shout-out was otherwise all-inclusive: "Finished strong and on to the next. That's an officially wrap on #FastAndFurious8. Thank you to our director @fgarygray for the vision and execution. Thank you UNIVERSAL for being tremendous partners as always, thank you to all my fellow co-stars for the daily effort and grind. Scott Eastwood you handsome sumbitch! Natalie Emmanuel I have a cold Budweiser ready for you and Tyrese Gibson you still have the biggest smile and forehead I've ever seen.😂"

He went on to praise the crew.

Though Vin and The Rock have not confirmed they are at odds, The Rock has promised to tell fans "everything"... once he has seen the completed film.
