KnoxvilleDunnDeath230.jpgWe caught up with Jackass creator Johnny Knoxville in LA on Tuesday, and offered our condolences for the sudden loss of his close friend/costar, Ryan Dunn.

Dunn died in a fiery crash early Monday morning, after Tweeting a pic of himself and his buds drinking at a bar in West Chester Pa, not too far from where the Jackass star grew up.

Movie critic Roger Ebert took to his Twitter to post a warning for those who drink and drive, but his message stuck a nerve.

Ebert Tweeted: “friends don’t let jackasses drink and drive” to his 480,000 followers, which prompted an outpouring of negative responses. Ebert’s Facebook page was immediately removed for violating Terms of Use, but came back online a few hours after.

When X17 asked Knoxville about Ebert's insensitive Tweet, the Jackass star replied, "I don't think too much about that guy."

Officials are awaiting toxicology reports to determine whether alcohol played a role in the crash, or if it was due to excessive speed.
