Johnny Knoxville car jackass sunglasses tattoos

Johnny Knoxville was keeping his sprits up while out and about in LA on Tuesday, and we offered our condolences for the sudden loss of his close friend and Jackass costar, Ryan Dunn.

Dunn was like a brother to the Jackass creator, so we can imagine how hard it's been for him, and the entire cast.

Dunn's blood alcohol level was more than twice the legal limit when he crashed his Porsche 911 around 2:30am Monday morning, killing both himself and Jackass member Zach Hartwell.

Knoxville and Hartwell worked on the second Jackass film together, and after finding out he was in the car with Dunn, Knoxville took to his facebook, expressing: "I would like to send my love out to the family of Zach Hartwell. I am very sorry for your loss."

We wish the Jackass family all the best during this difficult time.
