Even after being exonerated from child pornography charges, R. Kelly's legal troubles are not completely behind him. Detective Charles Freeman is suing the R&B crooner for failure to pay for services rendered.

According to the suit filed last week, Kelly hired Freeman to gather evidence for his child pornography case but skipped out on the $300,000 bill. Freeman's job was to "obtain and/or recover certain tapes that were said to incriminate" the Chicago native and states that he successfully completed the job. Aside from the unpaid monies owed, Freeman is also asking for damages, interest and other costs.

Last summer Kelly was found innocent of 14 counts of child pornography. The charges stemmed from Kelly's alleged videotaped sexual escapades with an underage girl. If convicted Kelly would have spent up to 15 years behind bars.

Earlier this year Kelly's divorce from his wife of 11 years, Andrea Kelly, was finalized. Andrea alleged that Kelly harassed, abused, and stalked her and filed an emergency restraining order against him in 2005.

The singer is currently working on his next album, which he announced at an Atlanta nightclub will be called 'Untitled' instead of '12 Play: Fourth Quarter' as previously reported.
