Jackass actor Ryan Dunn "was killed early Monday morning when his Porsche flew over a guardrail in West Goshen, Pa., slammed into a tree and burst into flames, according to local police," NBC Philadelphia reports. "Dunn's passenger — who hasn't been identified — was also killed."
As The Associated Press writes, "Dunn appeared on the MTV show that ran from 2000 to 2002 and its three big-screen adaptations. Most recently, he hosted Proving Ground on the G4 cable network."
He also appeared on NBC-TV's Minute To Win It.
Very early this morning, Dunn's Twitter page linked to a photo on Tumblr in which he appears to be enjoying some drinks with friends. (Update at 4 p.m. ET: It appears the tweet and photo have been removed.)
If you're not familiar with the Jackass TV show and movies, as IMDB says the premise is this:
"Johnny Knoxville and his band of maniacs perform a variety of stunts and gross-out gags."
Update at 2 p.m. ET. Knoxville posted this on his Twitter page:
"Today I lost my brother Ryan Dunn. My heart goes out to his family and his beloved Angie. RIP Ryan , I love you buddy."
