On Monday, Sharon was noticeably absent from The Talk, with co-host Julie Chen saying, "Sharon understandably took today off. We are sending all of our love to her and to her family and we ask that you do the same."
Meanwhile, a source in the salon tells ET that "it was known in the salon [Ozzy and Pugh] were a little too close," adding, "Michelle is super into rock/metal music, so they bonded over that. Still, it's weird. He's nearly 70 and a client. She knows better that to do this."
