Los Angeles, May 24 (IANS): Fashion designer Kelly Osbourne has tweeted the mobile number of her father Ozzy Osbourne's reported mistress.

Kelly took to Twitter and posted the number of hairdresser Michelle Pugh, who she believes was sleeping with the Black Sabbath frontman behind her mother Sharon's back, reports femalefirst.co.uk.

"Anyone looking for cheap chunky low-lights, a blow out and a b*** job, call ***********", Kelly wrote. 

The number has now been disconnected. 

One of Kelly's followers on Twitter questioned her actions and accused her of being "childish". 

"Kelly Osbourne, hate your father not the woman... He did this to your family... Again," the fan wrote. 

Kelly lashed out at the fan, saying: "Are you in my family? No, you are not... You have no idea what she did! So keep your high-mighty opinions to yourself!"

Kelly has supported her mother throughout the ordeal after Sharon, 63, found out about Ozzy's reported affair by reportedly searching through his emails.
