Ozzy, Sharon Osbourne Owe IRS $1.7 Million

The reality stars risk losing their home if they don't pay up.

Reality stars Ozzy and Sharon Osbourne have racked up over $1.7 million in unpaid back taxes.

The IRS has placed a lien on the couple's Los Angeles home until they return the money, TMZ reports. The Osbournes allegedly owe the government $718,948 from 2008 and $1.024 million from 2009.

This is not the first time the Osbournes have run into tax troubles. Last month, TMZ reported that the State of California filed a lien against their daughter, Kelly Osbourne, for $34,000.

Heavy metal singer Ozzy Osbourne and his family became household names when they starred in the MTV reality series The Osbournes in early 2000. The follow-up series, Fox's Osbournes: Reloaded, was canceled after one episode.
