Jack Osbourne will dive into a volcano as part of a stunt for his death-defying reality TV show.
Osbourne will jet to New Zealand on Wednesday (01Apr09) to start shooting the latest instalment of his show Jack Osbourne: Adrenaline Junkie, which follows his exploits as he travels the world seeking daredevil challenges.
The 23 year old's mum Sharon Osbourne reveals, "He's getting ready to go to New Zealand to bungee jump out of a helicopter into a volcano."
And the rock matriarch admits she and husband Ozzy constantly question their son's sanity: "We go back and forth on this. Is it better drinking and taking drugs or jumping out of a helicopter into a volcano?"
Now sober, Osbourne once checked into a teen rehab to kick his addiction to booze and prescription painkillers.
