The Internal Revenue Service has reportedly filed a tax lien against singer R. Kelly for $837,442.59.

The IRS filed the tax lien against the Grammy-winning R&B singer-songwriter in January 2010, according to the Detroit News. Last month, however, the IRS lifted an earlier tax lien for $1,036,858.

The singer, whose full name is Robert Sylvester Kelly, is also facing a $2.9 million foreclosure lawsuit against his mansion outside Chicago, according to Crain’s. He allegedly has not made mortgage payments since June of last year.

Kelly has had many hit songs, including "I Believe I Can Fly," for which he won three Grammy Awards in 1998. He has also produced and remixed songs for a number of artists, including the Isley Brothers, Luther Vandross and Vanessa Williams. However, he has also faced arrests and lawsuits for disorderly conduct, sex with underage girls, assault and other incidents.
