R&B singer Bobby Brown was released from the hospital Wednesday, after being transferred there from jail the day before.
DeKalb County Sheriff's Office spokeswoman Mikki Jones has declined to provide details about why he was hospitalized, saying inmates' medical information is confidential.
Brown, the husband of Grammy-winner Whitney Houston, had been serving an eight-day jail sentence sentence since last Friday, after pleading guilty to a 1996 drunken driving charge.
He also was released from jail custody Wednesday under a "good time" policy that reduces sentences by 25 percent for good behavior.
He was arrested Nov. 7 on charges of possessing less than an ounce of marijuana, speeding and having no driver's license or proof of insurance. After posting bond in Atlanta, he was transferred to the neighboring DeKalb County Jail to face the older charges.
Brown, 33, left R&B group New Edition in the late '80s for a solo career. His hits include "My Prerogative" and "Every Little Step."
He's had several brushes with the law, including a 26-day stint in a Florida jail in 2000 for violating parole on a 1996 drunken driving conviction by refusing a drug test.
In a recent interview with ABC's Diane Sawyer, Brown said he smoked marijuana, but did so to control his bipolar condition. In the same interview, Houston acknowledged taking cocaine and pills and smoking marijuana.
