The 32 year old's body was found at his home in Stratford, east London in March (10).
A hearing at London's Walthamstow Crown Court on Monday (08Nov10) revealed the star was found with a plastic garbage bag over his head, along with a canister of pleasure-boosting chemical ethyl chloride.
His passing was ruled as death by misadventure.

He later moved into TV and fronted a string of popular shows in Britain, including BBC's To Buy Or Not To Buy, Open House and Holiday.
