The IRS has placed a lien on their Los Angeles house, meaning if the Osbournes don't pay up soon, they're in serious danger of losing their home. Their daughter Kelly, 26, also owes the government money; TMZ reported that the state of California filed a lien against the actress for $34,000 last month.

Sharon wrote on her Twitter page Friday: "You can't rely on anyone but yourself. You have to be on top of your own business affairs. My fault..... lesson learned."
