Relatives of the 34-year-old daredevil - who died when his Porsche veered off road, crashed into a tree and burst into flames on Monday – were joined by pals including ‘Jackass’ co-stars Bam Margera and Johnny Knoxville and ‘It's Always Sunny in Philadelphia’ stars Glenn Howerton and Rob McElhenney at the four-hour “celebration” of his life in West Chester, Pennsylvania.

Ryan’s family flew to West Chester from Ohio and Florida to plan his funeral but the star is expected to be buried in Ohio where he was born.

A family member said: "We are devastated by the loss. Ryan will be greatly missed, but he will forever be in our hearts."

The memorial was held at the DellaVecchia, Reilly, Smith and Boyd funeral home ahead of the funeral which will be held later this week with a public memorial due to take place at a later date.

Toxicology reports have confirmed Ryan – whose close pal Zachary Hartwell was also killed in the crash – was more than twice over the legal drink-drive limit when he died.
