The "Mikshake" singer owes a whopping $300,426.17 in unpaid taxes for 2004 and 2010.
In 2004, Kelis went on tour with Britney Spears, while in 2010 the singer embarked on her very first headlining U.S. tour – she's now in trouble for not paying taxes on those profitable years. She's currently touring around Europe promoting new music, according to EURweb.
Her ex-husband Nas isn't doing any better. He was slapped with a tax lien earlier this year for failing to pay taxes in 2010 to the tune of $339,000. The government has reportedly placed a lien on his property.
Just last week, Lauryn Hill pled guilty to three counts of tax evasion for not paying taxes from 2005, 2006 and 2007. She faces up to three years in prison and $75,000 in fines.
