Fast & Furious star Vin Diesel has spoken on Facebook about a touching visit to Paul Walker's mother following the death of the 40-year-old actor.
Diesel revealed how he flew back to California when he heard Walker had died in the crash and "went directly from the plane to his (Walker's) mother's house".
"I thought they needed my strength, but realised when I got there and broke down before his family, that it was I who needed theirs," he wrote on Facebook.
"His mother hugged me and said 'I am so sorry' … I said: 'Sorry? You're the mother who lost a son?'... She said: 'Yes, but you lost your other half'."Walker died of the 'combined effects of traumatic and thermal injuries'
In the post, he paid tribute to Walker, saying: "I will always love you Brian (O'Conner, his character in the movie franchise), as the brother you were … on and off screen".
Walker, who starred in all but one of the Fast & Furious films, was killed when the Porsche he was a passenger in smashed into a lamp-post and a tree before bursting into flames last Saturday.
A coroner ruled that said he died from the "combined effects of traumatic and thermal injuries".Tributes have been left at the scene of the car crash
As a result of the tragedy, Universal Pictures has announced it is delaying filming of Fast & Furious 7.
Other Fast & Furious co-stars have also spoken of Walker's death.
Co-star Tyrese Gibson cried as he visited a memorial left at the scene of the crash, reportedly taking a piece of the wreckage in memory of his friend.
Ludacris, who has appeared in the film franchise, said on Twitter: "Your humble spirit was felt from the start. Wherever you blessed your presence you always left a mark, we were like brothers."
