The actor, who was a close friend of Paul, shared the details about Fast and Furious 7 with his 58 million Facebook fans.
"The last scene we filmed together, there was a unique sense of completion, of pride we shared… in the film we were now completing… the magic captured… and, in just how far we've come," he wrote accompanied by a picture of his final scene with Paul.
He continued: "Fast and Furious 7 will be released April 10th 2015! P.S: He'd want you to know first."
The news comes after it was rumoured that Paul's brother Cody had been asked to step in for him to film the final scenes for the action adventure.
Paul, 40, was on a break from filming when he was tragically killed in a car crash on 30 November. And in a poignant tribute to the star, Cody, who has worked as a movie stuntman, looks set to take his place in the latest installment.
"Producers had a string of meetings right after Paul's death," a source close to production told the Mail. "They soon realised they needed someone who looked like Paul to finish the movie, and that's when they approached his early identical brother Cody."
Cody, who lives in Oregon, has been staying in LA with his mum Cheryl as the family comes to terms with Paul's death.
The source added, "They can shoot Cody from behind and at a distance, and if it's a shot they need Paul's face in close up, they can CGI it later on.
"If Cody agrees it's because he wants to honour his brother's memory. There are many details that still need to be worked out, but right now the family and cast and crew are still grieving."
