Sharon Osbourne did not appear on “The Talk” on Monday after news of her split from husband Ozzy Osbourne following 33 years of marriage broke on Saturday.

Sharon, 63, is expected to return to the CBS show today after letting staff know over the weekend that she would be taking a “personal day,” a source told “Entertainment Tonight.” She is expected to address the breakup on-air when she returns.

“The Talk” co-host Julie Chen quickly addressed her absence on Monday's show.

“Now before we get started, as you can see, Sharon is not here today,” Chen said. “There were many tabloid headlines this past weekend about her and Ozzy, rumors and speculation that they have split up after nearly 34 years of marriage. 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 told “ET” that an extramarital affair is behind the Osbournes' recent split. The Sun, and English tabloid, was first to report that Ozzy, 67, had been having an alleged affair with 45-year-old hairstylist Michelle Pugh. Pugh, who works at Los Angeles hair salon Meche, was his hairstylist.

Ozzy is reportedly now staying at the Beverly Hills Hotel in California.

“At this time Ozzy is not at the marital home,” Sharon and Ozzy's spokesman, Gary Farrow, told “ET.”
