Last year, the ongoing feud between Dwayne "The Rock" Johnson and Vin Diesel seemingly ended last year when Johnson shocked Fast and Furious fans by appearing as Luke Hobbs in the Fast X mid-credits scene. Diesel had originally asked Johnson to come aboard back in 2021 to join the 10th installment of the long-running action franchise, but Johnson seemingly turned it down. It was a surprising ruse.

John Cena, who has also co-starred in the franchise, addressed the rumors concerning Johnson and Diesel on Dax Shepard's Armchair Expert podcast (via People). The WWE icon and action star said there were rumors but understood why. "There's certainly rumors about that. I can't deny that," Cena said. "You have two very alpha, driven people. You get two, there can only be one."

Cena was enlisted into the Fast family in F9: The Fast Saga as Jakob Toretto, the estranged brother of Diesel’s Dom Toretto. Cena said his early days in WWE prepared him to keep his head down and learn from more experienced players.
