Sharon Osbourne failed to appear on her US television chat show amid reports she has split up with husband Ozzy.
The 63-year-old is a panellist on daytime series The Talk but missed the programme after it was confirmed the Black Sabbath frontman was no longer staying at their home.
Sharon's co-host Julie Chen told viewers: "Now, before we get started, as you can see, Sharon is not here today. There were many tabloid headlines this past weekend about her and Ozzy. Rumours 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."
Ozzy, 67, has fought a public battle with drug and alcohol addiction throughout their 33-year marriage. He relapsed and this led to divorce rumours in 2013, but Sharon stood by her husband.
Reports suggest their current separation is not due to substance abuse issues. A spokesman for the couple said: "At this time Ozzy is not at the marital home."
Ozzy and Sharon met in the 1970s through her father Don Arden, who was managing the heavy metal group at that time.
She managed the Birmingham-born rocker before becoming his wife. The pair wed in 1982 and have three children together, Jack, Kelly and Aimee. Ozzy also has three children from his previous marriage.
The Osbourne family found a new level of fame when they appeared on MTV reality show The Osbournes from 2002 to 2005.
