R. Kelly entered a Chicago hospital yesterday for emergency surgery on his throat for an unknown condition.

The R&B crooner just wrapped up a 46 day tour with Keyshia Cole and Marsha Ambrosius, and complained of his throat hurting once he was back home. Kells also tweeted to fans that he was suffering from throat pains and was "sweating like crazy." 

Hopefully this isn't something serious.
