OZZY And SHARON OSBOURNE's Massive IRS Tax Lien

According to TMZ.com, the IRS filed a document last Monday with the L.A. County Recorder's Office, claiming Ozzy and Sharon Osbourne owe $718,948.25 for the 2008 tax year, and $1,024,175.03 for 2009.

Sharon had a tax lien issue in 2009 when she owed $23,000 to the State of California for the 2007 tax year.

Ozzy and Sharon recently listed their Malibu beach house on the market for $10 million.

The 4,500-square-foot, three-story oceanfront residence has five bedrooms and five bathrooms, along with a library, office, hot tub, walk-in closets and a backyard with a view of the Pacific Ocean.

The couple bought the house in March of 2003 for $5.1 million and first placed it on the market in 2006 for $14 million, with the place going on and off sale several times since then.

It's also available for rent starting at $40,000 per month.
