Jack Osbourne is going against fraught mother SHARON's advice and obtaining a sky-diving license for his new show JACK OSBOURNE: Adrenaline Junkie.

The 20-year-old son of rocker Ozzy Osbourne has decided to stop telling his TV presenter mother about the venture - because whenever he mentions it she starts crying.

He says, "Mum freaks out and starts bawling and that's just what I don't need."

Previous daredevil stunts on the show include mountain climbing and Thai boxing.
