Kevin Federline owes back taxes, the IRS claims.

Kevin Federline has an IRS bill of $57,000 according to a TMZ.Com report.

According to the celebrity news website, Britney Spears ex-husband was met with a federal tax lien.

The US Government wants their money owed and claims K-Fed has outstanding income tax bills for the years 2009 ($30,517.16) and 2010 ($27,098.23) that add up to just over $57K.

TMZ says K-Fed did some work in those two years, but they show a minimal effort.

According to the report, Kevin Federline had a bit part in American Pie: The Book of Love (straight-to-video) in 2009 and in 2010 he starred in "Celebrity Fit Club" on VH1.

He also receives a generous support package from ex-wife Britney Spears.

Another celebrity who owes the US Treasury is Snoop Lion as the IRS claims the rapper owes more than $546,000 in back taxes.

TMZ reports:

"Uncle Sam recently filed a federal lien against Snoop Dogg (Lion) -- real name is Cordozar Broadus -- claiming he owes $546,270.29 in unpaid tax bills.

According to the docs, Snoop owes for two separate years, 2009 ($101,952.44) and 2011 ($444,317.85).

It ain't Snoop's first brush with the IRS ... he reportedly owed $476k in back taxes back in 2008, but paid up when Uncle Sam brought the debt to Snoop's attention."
