The Osbournes have been handed another tax bill, for $357,000.

The reality TV family - headed by rock singer Ozzy and TV personality Sharon – had already received demands for $1.7 million, and their new bill for unpaid federal income taxes from 2007 brings their debt to the US government past the $2 million mark.

Sharon has taken responsibility for the situation, admitting she has not met with her accountant due to her busy schedule.

She said: "I'm to blame. Even though the accountant is paid to do a job, the buck stops with me. I was too involved with myself. I cancelled two meetings with him over the last 18 months because I was way too busy."

Although they have been hit with the huge bills, the Osbournes have moved quickly to clear them, having reportedly settled the $700,000 and $1 million debts from 2008 and 2009 respectively, which they have previously received.

Sharon added: "I hope none of this reflects negatively on mine and Ozzy's moral character."
