Pamela Anderson has a tax debt of over $440,000, a new report says.

The 45-year-old Baywatch star has been hit by two separate tax liens from the US government, ordering her to pay her unpaid taxes in 2011 immediately.

The first lien was filed by the Inland Revenue Service (IRS), claiming Anderson owes $310,000 for 2011 taxes, while the State of California also says the she owes a further $134,000 for 2011, according to TMZ.

The Dancing with the Stars: All Stars contestant - who was axed from the ballroom dancing contest in the first round - has previously had tax problems, notably in 2009 when she was hit with a lien for a whopping $1.7 million.

Pamela has even been blacklisted on California's list of "Top 500 Delinquent Tax Payers" in the past.

Anderson has recently signed on to British talent show Dancing on Ice in a bid to ice skate her way to victory - and the prize money.

A source previously commented: "Pamela will bring a bit of Hollywood glitz and glamour to the show, which we will all need come the winter.

"She's no stranger to dancing in front of viewers after her stints in America."
