Kelly Osbourne turned into a crime-fighting super hero for a day!

Okay not “really” … but she did stop not only one, but TWO crimes in one day in London Monday (Jul 11).

After spotting two boys attempting to break into a vehicle in London, the 26-year-old reality TV personality and singer intervened on the scene of the attempted crime. Kelly apparently didn’t have to do much to scare the perps off, as she later revealed in a post on her Twitter page post-saving the day.

“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!” Kelly tweeted.

And Kelly’s crime fighting doesn’t stop there. Later that same day, she saved the day again, tweeting “WTF is going on tonight just stopped 2 boys with lacrosse sticks trying to push Gee-Wizz [small electric car] 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—ing [TV show] crime watch!” she added.
