Ryan Dunn, one of the stars of MTV's "Jackass," has died in a car crash. He was 34 years old.

NBC Philadelphia reports that Dunn and another passenger died in a tragic 3 a.m. crash at Route 322 and New Street in West Goshen Township, Pennsylvania.

The news of the death was confirmed by April Margera, mother of "Jackass" star Bam Margera, in an interview with a local radio show. Bam also confirmed the sad news with TMZ.

Dunn posted a photo of himself drinking with friends just hours before the crash.

A police report indicated that Dunn was most likely speeding in his 2007 Porsche 911 GT3, which was destroyed in the wreck. "Upon arrival, police located one vehicle in the road and in the woods that was fully engulfed in flames, " the report said. 'DUI' was not indicated in the report.

Known for his fearlessness, Dun was perhaps best known for his parts in crashing golf carts and placing a toy car - in a condom - up his rectum in the original "Jackass" film. 

Co-star Johnny Knoxville expressed his devastation via Twitter, saying, "Today I lost my brother Ryan Dunn. My heart goes out to his family and his beloved Angie. RIP Ryan, I love you buddy. http://say.ly/hUnqQQ"
