Kelly Osbourne stopped two boys from stealing a car.

The TV star was in London last night (11.07.11) when she came across the hoodlums trying to break into a parked vehicle, but after startling them in the act they ran off.

She revealed on his twitter account: "Just stopped 2 boys robbing a car all I said was 'oi' and they ran like the wind. I did not realise I was that scary!"

Amazingly, Kelly's crime-fighting wasn't finished for the evening as she later stumbled across two more boys trying to push an electric G-Wiz car on its side.

She added in other tweets: "WTF is going on tonight just stopped 2 boys with lacrosse sticks trying to push Gee-Wizz car on it's side what's wrong with London police?

"I'm in one of the poshest parts of London and it's like f*****g crime watch! (sic)"

The 26-year-old blonde was more enraged with the lacrosse stick-wielding vandals than the foiled thieves.

In an other angry twitter posts, she wrote: "You know what I get the first 2 with the state of the economy but the 2 rich t**ts with there lacrosse sticks disgust me more stupid t**ts!

"Night night dodgy london! (sic)"
