*Legendary vocalist Etta James has been hospitalized for a serious infection that appeared to develop while she was being treated for substance abuse, her son told the Associated Press.

Donto James says his famous mom, 72, checked into Riverside Community Hospital about a week ago and is now on the mend from sepsis caused by a urinary tract infection.

He says James, who lives in Woodcrest, Calif., entered a drug treatment program about a month ago to shake a dependency on painkillers and over-the-counter medicine. She was transferred to another facility and then the hospital when her physical condition worsened.

James, who sang everything from blues to jazz, is best known for the hit “At Last.”
