Singer Natalie Cole will need more than a month in order to recover from a relapse in her battle with hepatitis C and has thus canceled an upcoming concert tour, reports The Associated Press.

Representatives for singer and actress Natalie Cole, the daughter of iconic jazz musician Nat King Cole, said Friday that she has been hospitalized to receive treatment for hepatitis C.

Natalie Cole first revealed her health problems in July. She said at the time that the disease, which affects the liver and spreads through contact with infected blood, was diagnosed during a routine check-up. She said she probably became infected due to drug use in her youth.

The 58-year-old has been in a New York City hospital since Sept. 12. Publicist Maureen O’Connor of the firm Rogers & Cowan said Cole was expected to remain for several more days in the hospital and then return to her Los Angeles home, where she has been ordered to bed rest by her doctors.

O’Connor further said that Cole had been responding well to treatment for hepatitis C but that she had recently been going through a more exhausting time, what with her busy promotional schedule and the inevitable side effects from the medication she takes.

“We are canceling her activities in October, but we do expect her to have a complete recovery,” she said. “She just needs some rest.”

Among the activities cancelled is a concert tour which was scheduled to kick off Oct. 3 in support of her new album, “Still Unforgettable,” released last week.

Natalie Cole made her debut as a singer with 1975’s “Inseparable,” and a glorious debut it was as she received a Grammy Award for Best female R&B Vocal Performance (for the single “This Will Be (An everlasting Love)”) and another for Best New Artist in 1976.

Her 1991 album “Unforgettable… With Love,” which saw her remake some of her legendary father’s greatest hits, earned her multiple Grammys and went platinum in the US.

The newly released “Still Unforgettable” features classics rearranged by Cole, including a virtual duet with her father, a cover of his 1951 hit “Walkin' My Baby Back Home.”
