Angela and Vanessa Simmon's may be in trouble with the IRS as they reportedly owe almost half a million dollars in unpaid.
The girls, who are daughters of Run-DMC founder Rev Run, appear to have failed to pay more than $450,000 dating back to March 2010.
According to legal documents obtained by DetroitNews, both Angela and Vanessa have tax liens against them, filed by the State of California and New York.
Angela owes the most, raking up a $225,910 bill, while Vanessa owes $224,568.
The website claims to have contacted the girls but they are yet to reply.
