Kings of Leon Salute Ryan Dunn at London Show

While close friends and family mourned the loss of "Jackass" star Ryan Dunn during a Wednesday memorial service, Kings of Leon paid tribute to their late pal across the pond.

During their set at London's Hyde Park, frontman Caleb Followill asked the crowd to raise a glass to "a friend of ours who passed away." The rockers then began playing "McFearless," declaring, "this is for Ryan."

Jared Followill spoke out on Twitter earlier that week, posting: "I'm heartbroken to say that our great friend we made over the last 8 months has passed away.  Honestly in shock. Devastated. RIP Ryan Dunn."

Dunn's "Jackass" co-star Jason "Wee Man" Acuna paid a more permanent tribute to his friend in the form of a tattoo. Acuna had a photo of Dunn's face inked on his lower leg with the phrase "Random Hero!"

"After Ryan passed away, [I asked] how can I do something for Ryan?" he explains in a video. "Well, it's something he'd probably do for any one of us if it was one of us in the situation. I'm going to get him tattooed on me. Yep, that's what I'm going to do."

Dunn was killed early Monday morning, along with passenger Zachary Hartwell. According to police, Dunn was driving at least 130 miles per hour with a blood alcohol level more than twice the legal limit. His Porsche burst into flames after crashing into a tree.
