Kelly offers the mistress number that tore her family apart

Kelly Osbourne has taken to Twitter to hit out at Michelle Pugh – the woman who is accused of having an affair with Kelly's dad, Ozzy Osbourne.

Kelly, 31, tweeted hairstylist Michelle's number with the message: "Anyone looking for cheap chunky LOW-lights a blow out and a blow job call..."

Ouchie…Before you try ringing Michelle's number for a new 'do or, erm, something else, don't bother – it's been disconnected. Probably not a bad idea.

Kelly also got into a Twitter fight with one of her followers who suggested that maybe Ozzy, 67, was at fault too. She wrote to Kelly: "@KellyOsbourne hate your father not the woman.. HE did this 2 ur family ... Again. #SMDH #childish."

Kelly responded: "Are you in my family? NO YOU ARE NOT YOU HAVE NO IDEA WHAT SHE DID! So keep ur high-mighty opinions to yourself!"
