'Jackass,' MTV Stars And Other Celebrities React To Ryan Dunn's Death (TWEETS)

"Jackass" star Ryan Dunn died last night in a tragic car crash at the age of 34.

The film and television actor apparently crashed his car around 3 a.m. EDT last night at the intersection of Route 322 and New Street in West Goshen Township, Pennsylvania. TMZ confirmed the death with April Margera, the mother of fellow "Jackass" star Bam Margera.

Though no official cause for the accident has been determined as of yet, Dunn posted this picture of him drinking on his Twitter account, shortly before the believed time of the accident.

There has been little word from Dunn's close friends and "Jackass" collaborators since the accident. Bam Margera, Johnny Knoxville, and Steve-O are all yet to have said anything about his passing on Twitter.

However, Jason 'Weeman' Acuna did post about about his friend's passing.

You can see his and other celebrity reaction below, as well as MTV's official tweet on Dunn's passing.

UPDATE: Johnny Knoxville has since reacted to the loss of Dunn via Twitter. His tweet is listed in the slideshow below.
