Everyone who’s seen Fast & Furous knows what a tough guy Vin Diesel can be, but even he realised there’s a breaking point.

The actor raced to the home of Paul Walker’s mother after learning about his movie co-star’s death, believing that he could offer some sort of solace.

In a heart-breaking post on his Facebook page on Friday, the 46-year-old actor revealed how he jumped on a plane to California to be by Cheryl Walker’s side just hours after Walker, 40, died in a car crash on November 30.
