Biker Jack Osbourne

Jack Osbourne has bought a new super-bike.

The 'Adrenaline Junkie' TV star - the son of rocker Ozzy Osbourne and 'America's Got Talent' judge Sharon - has a need for speed and has splashed out thousands on a Ducati 848.

His sister Kelly said: "My brother Jack loves motorbikes and last week he bought a Ducati 848. He is so proud of it. Jack and I are the same like that - we get so excited about new things."

Although Kelly and Jack's parents were able to shower their children with gifts due to their wealth, the 25-year-old beauty insists she and her siblings - which includes sister Aimee - were never spoilt.

She added to Closer magazine: "We know that we've had overly privileged lives but our parents have always taught us to never take things for granted."
