LOS ANGELES, Aug. 4 (UPI) -- Kelly Osbourne is facing a lawsuit from her father's mistress, hairstylist Michelle Pugh.
In May, when news of Ozzy's years-long affair with Pugh broke, Kelly unleashed a series of tweets directed at Pugh – even tweeting out Pugh' phone number and claiming Pugh abused the 70-year-old rocker.
