Natalie Cole, who recently revealed she had hepatitis C, has been hospitalized as a result of side effects from her medication and a heavy promotional schedule, her representative said Friday.

The Grammy-winning singer has been in a New York City hospital since Sept. 12, and is expected to remain there for at least a few days, according to publicist Maureen O'Connor of the firm Rogers & Cowan.

Cole announced in July that she was suffering from hepatitis C, a liver disease spread through contact with infected blood. She said at the time that the disease was revealed during a routine examination and was likely caused by her drug use years ago.
