Jackass star Ryan Dunn dies in car accident

Ryan Dunn, who will forever be known for sticking a Hot Wheels car up his own ass in the movie "Jackass," and another as-of-yet-unidentified person, both died in a crash outside of Philadelphia early this morning.

Police say they don't know whether the 34-year-old Dunn, who appeared in all of the "Jackass" movies, or the unidentified person was driving the car. The shot up top was taken at the scene of a one-car accident that took place in West Goshen, Pa. around 3:30 AM Monday morning.

Police also don't know whether alcohol was to blame — but Dunn did tweet out the following picture from his Tumblr account hours before his death.

Our guess is that isn't an iced tea he's drinking.

UPDATE: MTV just tweeted out the following statement: "We're deeply saddened by the passing of a member of the MTV family, Ryan Dunn. Our hearts and thoughts are with his friends and family."

UPDATE 2: This is a photo of what Ryan Dunn's Porsche 997 GT3 looked like before the deadly accident — we're obviously still assuming that this was the vehicle being driven. We've received no confirmation yet on whether that's the case.
