Celebrities have come together to pay tribute to Ryan Dunn, who died in a horrific high-speed car crash in the early hours of Monday morning.

The ‘Jackass’ star, aged 34, and his pal Zachary Hartwell, were killed after the stuntman’s Porsche reportedly careered off the road and burst into flames in Pennsylvania.

Leading floods of heart-felt messages on Twitter was his close buddy and MTV co-star Steve-O, who told fans,

“I don’t know what to say, except I love Ryan Dunn and I’m really going to miss him.”

Good Charlotte guitarist Benji Madden also paid his respects to the star online, posting,



“I’m very Sad and Shocked to hear about Ryan Dunn,” while his bandmate and brother Joel added, “R.I.P Ryan Dunn. Very sad news.”

‘Hills’ star Brody Jenner expressed his condolences too, writing,

“Just heard about Ryan Dunn… So sad.. #RIPRYANDUNN.”

And popstar Jessica Simpson, who starred in the flick ‘Blonde Ambition’ alongside the famous daredevil, added,



“It has taken me all day to put my thoughts into words, but there are no words to describe the loss of such an incredible man. RIP Ryan Dunn.”
