VIDEO : Kelly Osbourne Tweets Foul-Mouthed Rant Against Ozzy's Alleged Mistress

Kelly Osbourne has tweeted the mobile number of her dad Ozzy Osbourne's alleged mistress, along with a foul-mouthed rant against her. The angry fashion designer has lashed out on Twitter and posted the digits of hairdresser Michelle Pugh, who she believes was sleeping with the Black Sabbath legend behind her mother Sharon's back. The outspoken star has supported her mother throughout the ordeal after Sharon found out about Ozzy's alleged affair by reportedly searching through his emails. When some fans responded to Kelly's tweet with reminders such as "It takes two to tango," Osbourne blasted them back with even more anger and profanity.
