John Abraham and Mahendra Singh Dhoni are friends. And obviously when John requested the cricketer to attach the trailer of his next film, Force 2 to M S Dhoni - The Untold Story, the cricketer, who is involved in the marketing of the film made sure it happened. Says a source, “John and Dhoni go way back. In fact, the actor was one of the few privileged enough to know several real life stories of our Captain Cool. John was the only Bollywood star to attend Dhoni’s marriage to Sakshi in Dehradun six years ago.”
