Jack Osbourne 'bored' of partying sober

Rocker Ozzy Osbourne's son Jack has discovered a huge downside to his successful sobriety - he now finds parties "boring".

The 18-year-old reality TV star entered a rehabilitation centre last year to beat his addiction to painkillers, and while he's proud of overcoming his dependency, his decision to also give up alcohol has made his social life comparatively tame.
