Ryan Dunn, one of the stars of the "Jackass" movie series, has died in a car crash in Pennsylvania, the mother of a co-star confirmed.

Dunn, 34, and an unidentified person both died in the crash early Monday, the mother of Dunn's "Jackass" co-star Bam Margera told TMZ.

In the last photo Dunn posted to Twitter, he and two friends are seen drinking, MTV News reported.

The car reportedly caught fire in the crash in West Goshen Township.

It was unclear who was driving the car, authorities said.

Dunn started doing extreme stunts and skateboard tricks in a series of online videos and joined MTV's "Jackass" in 2000.

He appeared in "Jackass" spin-offs like "Viva La Bam" and "Bam's Unholy Union," as Bam Margera's sidekick.

He also acted in the Jessica Simpson movie "Blonde Ambition" and on the NBC drama series "Law & Oder: SVU."
