If you mess with Kelly Osbourne’s family, know that she’s gonna mess with you back. While rumors swirl that Ozzy Osbourne allegedly cheated on his wife, Sharon, with hair stylist Michelle Pugh, Kelly’s taking action.

Yesterday, Kelly Osbourne tweeted out “Anyone looking for cheap chunky LOW-lights a blow out and a b—w job call …”. And yes, she really did it!

She tweeted in defense of her mother, in recent news that her father has been having an affair with hair stylist Michelle Pugh. Allegedly Kelly and her mother Sharon, 63, have called the salon several time to reach contact with Michelle.

Sources say the tweet is an example of Kelly’s protective nature.
