According to “Us Weekly”, SHARON OSBOURNE found out about OZZY’s affair by checking his emails.  It’s not clear if she suspected him first, or if that’s just something she does . . . which really wouldn’t surprise me. Anyway, that’s how she found out he was having an affair with a celebrity hairstylist named Michelle Pugh.  She was working at a salon in Beverly Hills at the time, but he was basically supporting her. Obviously Sharon hit the roof.  She and her daughter KELLY called the salon repeatedly for two weeks to get in touch with her.  And it got so ridiculous, Michelle actually lost her job. Sharon’s back on “The Talk” after taking Monday off, but so far she hasn’t actually said that Ozzy cheated.  Ozzy only released one statement, where all he said was that the breakup had nothing to do with his sobriety.
