Jack Osbourne, youngest child of Ozzy and Sharon Osbourne, was shopping London’s Marylebone High Street on Saturday when he saw a man snatch a woman’s purse.  Before you could say “Perfect PR Op” the recently slimmed down Osbourne instantly put his workouts into action and took off after the mugger.  Osbourne caught the man, pinned him on the ground, and with the help of a couple other people, held him there until the police arrived.

The 14-stone fitness fanatic and martial arts fan told the News of the World: “I could see the girl was in trouble, it just felt like the natural thing to do. I’m glad it turned out okay.”

A source said of the host of ITV2’s Adrenaline Junkie: “He was amazing. He ran after the mugger like a man possessed—a real hero.

“It happened so quickly. But Jack spotted it, easily beat him in the race over 20 metres and pushed him to the ground. Whatever technique he used meant the robber couldn’t escape.

“The girl was very grateful, but Jack was very modest.”

It would appear Jack could be turning into a pretty decent guy.  He’s working hard on Adrenaline Junkie, staying out of trouble, getting healthy and fit and now, rescuing damsels in distress in the streets of London.  I’m glad to see it because I always thought he was worse than Kelly on The Osbournes.  His general attitude seemed more entitled while Kelly’s was rebellious, kind of like the difference between Paris Hilton and Nicole Richie the first season of The Simple Life.

Jack must have taken his reality stint on Armed and Famous alot more seriously than one would have thought.  Osbourne went through police training alongside Eric Estrada, LaToya Jackson, WWE’s Trish Stratus and Wee Man of Jackass in the flop reality show.  The show was a disaster and didn’t even last a season, but now they can say something good came of it.  Now if LaToya would just contribute to society it might all be worth it.
