R&B star R. Kelly [ tickets ], already facing a 21-count indictment for child pornography possession in Chicago, was arrested in Florida on an additional 12-count charge.

Kelly was arrested on Wednesday (1/23) morning at a Miami hotel, and was released on bail later in the day.

According to the Chicago Sun-Times, Kelly had received a court's permission to go to Miami to tape a music video for his new song "Ignition."

Kelly was arrested in Florida last June on a Chicago warrant stemming from a videotape that allegedly shows the R&B star having sex with a 14-year-old girl. When police served the warrant on Kelly at his Florida home, police found "12 digital images of Kelly and/or a nude underage girl" during a search, authorities told the Sun-Times.

The six-month delay in filing the charges was so that police could positively identify the people in the photographs, according to news reports.

Kelly has consistently maintained his innocence, and his attorneys said the new charges stemmed from the same issues covered by the Chicago indictments.

"At this point, it looks to us like a classic case of piling on, in which a local jurisdiction tries to make headlines by attaching itself to a celebrity case," Kelly lawyer Marc Martin said in a statement. "As far as we can tell, the charges all relate to R. Kelly's arrest last summer. In other words, there is nothing new here."

Kelly, who is free on bond, has his next court date in Cook County, Ill., on Feb. 7.

A new Kelly album titled "Chocolate Factory" is due in stores on Feb. 28. The self-produced album will be packaged with a 6-song bonus CD featuring songs from Kelly's unreleased album "Love Land," the tracks from which are circulating widely on the Internet.

Among the songs on "Love Land" is "Heaven I Need a Hug," a single that Kelly released after his first arrest.
