Vin Diesel on Paul Walker's Death 3 Years Later

— -- Vin Diesel said he is still reeling three years later after losing his dear friend Paul Walker.

Walker died in 2013 after the car he was riding in crashed and caught on fire.

"The last three years have been some of the hardest of my life because of losing my brother like that," Diesel told Entertainment Tonight about Walker.

In fact, he spoke to ET at Brazil Comic-Con and said being there felt wrong, being that "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," he said. "But the irony is the whole cast reached out and his daughter, Meadow, reached out and all that stuff helps you get through it.”

Diesel was in Brazil also promoting his new "xXx" movie and said after finishing "Furious 7" without Walker, this was a welcome change. Diesel had worked with Walker on the "Furious" franchise since it began 15 years ago.

"Never in my life did I need to do a movie where I could laugh and smile and enjoy myself more than right now, more than the time I made this movie," he said.
