Losing a friend is always hard, and 'Jackass' star Bam Margera lost his very best friend when Ryan Dunn died in a violent car accident last week.

"It was pretty much the worst news I've ever heard in my life," Margera told E! Online while sitting next his wife, Melissa "Missy" Rothstein.

"He was my best f--king friend in the world. It's been five days now and I can't stop crying man," a visibly upset Margera said. "I just don't think it should've been him."

Though news of Dunn's death came as a shock -- Margera woke up to the news in Arizona -- the 'Jackass' star's reckless driving didn't come as a surprise.

"He flipped me in a car eight times at the same exact spot in 1996," Margera said. "Thank God I had my seat belt on, because ['Jackass' star] Chris Raab put one on me, but my brother didn't have one on. He flew 40 feet. Thank God he's alive. But like, Dunn was always a maniac at driving."
