The complaint states that Kelly hasn't made monthly mortgage payments since June of last year. Crain's reports the Olympia Field home's appraised value fell 26 percent in a year, to $3.8 million in 2010. The original 1999 loan was for $3.5 million. The principal due is more than $2.9 million.

The R&B superstar's spokesman Allan Mayer declines to comment on the foreclosure. But says that Kelly isn't having financial trouble. Mayer says the singer now lives in Chicago. Mayer says Kelly's recent tour and 2010 album, "Love Letter," have been successful.
