There had been rumors that Dwayne Johnson was going to be joining the cast of Fast Five. Now it appears that those rumors have some validity based on a recent post from Fast Five co-star Tyrese Gibson. At his Twitter account he wrote:

Major shouts to Vin Diesel, Paul Walker, & Dwayne "Rock" Johnson!! "Fast & Furious Five" Let's get em again!!

Collider is also claiming that that their sources are confirming this and that there should be an official announcement shortly.

Also, Ludacris also sent out a message via Twitter that he too was coming back for Fast Five:

Just landed in Puerto Rico. Shooting for Fast & Furious 5 is about to be underway.....

Tyrese Gibson and Ludacris are no strangers to this franchise having both been in the second film 2 Fast 2 Furious.

We will have more on these casting reports as they arrive.
