The Osbournes, who have been married more than 30 years and are the parents of three adult children, hit a rocky patch in their relationship when recovering drug addict Ozzy suffered a relapse and was abusing substances for more than a year.
Despite their recent separation, both Sharon and Ozzy have publicly said they have no plans to divorce.
The New York Daily News said the television personality and her rocker husband have been trying to work out their problems and were seen looking affectionate Saturday night at a gala event.
TMZ said the couple had met for lunch earlier in the day.
