Ozzy and Sharon Osbourne owe over $1.7 million in unpaid back taxes and the IRS has placed a lien on their home, reports E! Online.
Sharon addressed the issue on Twitter, insinuating that the issue was caused by the family's accountant.
"You can't rely on anyone but yourself. You have to be on top of your own business affairs. My fault... lesson learned," Sharon wrote on Twitter. "Just because you're paying someone doesn't mean they're doing the job correctly."
The reality stars reportedly owe the government $718,948 from 2008 and $1,024,175 from 2009. The IRS has placed a lien on their Los Angeles mansion in Hidden Hills until they return the money, according to papers filed in the L.A. County Recorder's Office. Their Malibu vacation home is reportedly another target.
Last month, it was reported that their daughter Kelly Osbourne also owed $34,000 in unpaid taxes and the state of California had filed a lien against her as well.
The heavy metal Black Sabbath rocker and his family reached reality stardom with their MTV show "The Osbournes," which premiered in early 2000. The follow-up series on Fox, "Osbournes: Reloaded" was canceled after one episode.
Sharon Osbourne is currently one of five co-hosts on the daytime series, "The Talk." She was also a judge on talent shows like "The X Factor" and "America's Got Talent."
The couple is expected to make the back payment within the next week.
