Rock singer Ozzy Osbourne and his wife Sharon have been hit by another tax lien from the Internal Revenue Service, putting their tax debts at more than $2 million.

The second tax lien is for $357,070.62 for unpaid federal income taxes from 2007, according to TMZ.com. Last month, the IRS placed a lien on the Osbournes’s Los Angeles home saying that they owed over $1.7 million in back taxes from 2008 and 2009 (see Ozzy and Sharon Owe $1.7M to the IRS).

Sharon Osbourne admitted at the time to losing track of her finances. On her Twitter page last month, she said, “You can’t rely on anyone but yourself. You have to be on top of your own business affairs. My fault...lesson learned.”

She later admitted on her chat show “The Talk” that she had been too busy and had postponed meeting with her accountant.

“I got really upset with my accountant, and then I sat back and I thought ‘If I’m not invested in my money, or my kids’ money, or my husband’s money, why should he?’ He did say he’s to blame, but I’m to blame because I didn’t care enough,” she said. “I was too involved in myself. I canceled two meetings with him over the last 18 months because I was way too busy. And the bottom line is it stops with me. So I have to face up, be a big woman and realize I’m not Mrs. Wonderful.”

However, in a Twitter entry on Sunday about the latest IRS tax lien, she had a different opinion. “Just when we thought it was safe with the IRS, here they come again! This time their fault, not mine. Not taking this one laying down," she wrote, adding, "Mine was a f**k up, yours was a 'PROCEDURAL ERROR.' The bill has been paid, in fact I’m owed a rebate. Please send. Big Kiss, Mrs O."

The Osbournes’ daughter Kelly has also fought against reports that she owes unpaid taxes (see Kelly Osbourne Disputes Tax Debt Rumors).
