Jack Osbourne

Jack Osbourne is the son of musician Ozzy Osbourne and ITV favourite Sharon Osbourne.

Jack shot to fame in 2002 after appearing in the hugely successful MTV show The Osbournes.

In the show Jack was mostly shown as a rebellious teenager who liked to party and fight with his sister Kelly.

In 2005, Jack started to show more of an interest in fitness which lead to him co-hosting the ITV show Celebrity Wrestling: Bring It On!

The same year Jack appeared in Extreme Celebrity Detox, in which he took part in T’ai Chi and climbing exercises. It was during this time Jack overcame his childhood fear of heights and found a new passion for adventurous sports.

Jack was discovering a natural high from exercise and extreme sports which inspired him to appear in his own show, Jack Osbourne: Adrenaline Junkie.

Over the four series, Jack has tried rock climbing, mountaineering, bungee jumping, white water rafting, martial arts, running with the Bulls and many more.

Let's hope he's up to his Beat The Star challenge.
