Add R. Kelly to the list of celebrities who have gotten in hot water with the Internal Revenue Service for not ponying up their fair share of taxes. Joining the likes of Lil Wayne
 and Lauryn Hill in the IRS doghouse, TMZ reported that Kelly owes more than $4.8 million in taxes dating back to 2005.

A rep for the singer said, "R. Kelly is in the process of working everything out with the government and is confident that all his obligations will be satisfied."

The breakdown of the alleged non-payments includes: $1,472,366.77 (2005), $710,520.51 (2006), $376,180.11 (2007), $1,122,694.90 (2008), $173,815.18 (2009) and $992,495.24 (2010). The total bill comes to $4,848,072.71.

After taking some time off to recover from emergency throat surgery
 last year, Kells is expected to make his music return later this month with his 11th studio album, Write Me Back.

The lead single from the disc, "Share My Love," was released in February and a second song, "Feelin' Single" hit late last month. The disc is the follow-up to 2010's Love Letter, an ode to Kelly's favorite music from the 1950's and '60's.

In December, Kelly shocked fans when he announced that he would be adding 32 chapters to his popular "Trapped in the Closet" series, and in March it was confirmed that the series would be aired on IFC later this year. Twenty-two chapters exist thus far in the soap opera series that begins with a one-night stand and weaves into an extended tale of sex and lies, starring Kelly's alter ego, Sylvester.
