R. Kelly is recovering in a Chicago hospital after undergoing emergency throat surgery.

The Chicago singer went to the hospital and had the surgery performed, but no further information has been released about the seriousness of his condition. Last week, Kellz expressed problems with his throat over the popular networking site Twitter, typing, “I refuse to take another cup of theraflu! I feel like my throat is coming back. I’ve been in bed sweating like crazy. Thanks guys!”

He recently finished a 46-day U.S. tour with Keyshia Cole and Marsha Ambrosius.
