While a source close to the Osbournes told ET that the alleged affair has been "hard on the family," Sharon Osbourne -- who is her husband's manager -- was on hand to introduce the 67-year-old musician during a press conference in Hollywood, California, on May 12. Kelly was also in attendance.

However, Sharon told ET that that the estranged couple's appearance together was strictly professional. "It's business. This is my business, you know? This is what I do," the 63-year-old talk show co-host explained. "People have forgotten because they see me every day on the chat show, but this is still the other half of my life."
