Vin Diesel struggling with Paul Walker`s death

London: Actor Vin Diesel is still mourning the loss of Paul Walker and says he is struggling to cope with the painful void since his co-star died in a car crash on November 30 last year.

`The Fast and the Furious` star Walker died alongside his friend, Roger Rodas, when their car crashed and burst into flames in Santa Clarita, California.

Diesel, 46, posted a picture of himself laughing with his late co-star while on a press tour for their latest film from the franchise on Facebook, reported Contactmusic.

"There was always moments of child-like laughter... We had accomplished so much by 2013... PS. The complexities of Brotherhood, and the painful void... Of it`s absence," Diesel wrote.

The actor revealed late last month that `Fast & Furious 7,` which he began filming alongside Walker in September, will be released on April 10, 2015, even though they were on a break from shooting when the star passed away.
