Jack predicts tears on Evans' show
Jack Osbourne will be providing commentary for Chris Evans' new live Channel 4 show in which celebrities perform hair-raising stunts.
Famous And Fearless, which starts on Sunday, features eight celebrities who take on urban and extreme sports ranging from BMX and Powerbocking to Car Flips and Demolition Derby.
Jack, 25, who conquered stunts around the world in Jack Osbourne: Adrenaline Junkie, said: "Basically I'll be predicting which celebrity will win and who will be the first to cry.
"The challenges are really tough - even more so when you're stood in a packed arena, live on national television. It's as much about mental strength as physical fitness."
Former EastEnder Kacey Ainsworth and ex-Atomic Kitten Jenny Frost are among those to have signed up to the new entertainment action show.
Famous And Fearless will be presented by Radio 2 DJ Chris and BBC sports host Clare Balding live from January 2 to January 7 from the Echo Arena Liverpool.
Other names to have signed up include double gold Olympic medal winner Dame Kelly Holmes, former Hollyoaks star Sarah Jayne Dunn, Sir Richard Branson's son Sam Branson, adventurer Charley Boorman, comedian Rufus Hound and New Zealand rugby legend Jonah Lomu.
Tickets to watch the celebrities at the Echo Arena Liverpool are free.
