Vin Diesel says the three years since Paul Walker's death have been the "hardest of my life" (photos)

Vin Diesel says the last three years have been the "hardest of his life" since the death of his good friend Paul Walker.

The Fast and Furious actor - who is currently in Brazil promoting his new movie xXx: Return of Xander Cage - admits it was tough being in the South American country because he had always been with Paul when he visited there in the past.

He said: "We’ve felt the loss. The last three years have been some of the hardest of my life because of losing my brother like that ... I’d been to Brazil two times before and both times that I’ve been here, I’ve always been with my brother, Pablo ... It was a lot of tissues and it was a hard morning for me yesterday because I was here.

"But the irony is the whole cast reached out and his daughter, Meadow, reached out and all that stuff helps you get through it."

And the 49-year-old actor enjoyed filming the action thriller series as it gave him an opportunity to "laugh and smile". Photos of them in the past  movie shootings...
