The Jackass star's off-the-wall stunts made him a star on MTV – that seemingly reckless abandon cut the daredevil's life short at age 34. On June 20, an intoxicated Dunn crashed his Porsche on a Pennsylvania highway, killing him and a friend. "Today I lost my brother Ryan Dunn," Jackass co-star Johnny Knoxville Tweeted. "My heart goes out to his family and his beloved Angie [Cuturic]. RIP Ryan, I love you buddy."
