Grammy award-winning singer Natalie
Cole has filed for divorce from Kenneth Dupree, her husband since October 2001.
Natalie Cole's first album was released in 1975
Cole, 53, cited irreconcilable differences for the decision to end her third marriage. Cole's publicist said she was unavailable for comment.
Cole is best known for Unforgettable, With Love, the 1991 album which combined her voice with that of her late father, jazz great Nat King Cole.
The album sold 14 million copies and won the Record of the Year Grammy.
The singer performed a rendition of You Are So Beautiful to Me at a pre-wedding party for Liza Minnelli in March last year. Minnelli and husband David Gest are now in the middle of divorce proceedings.
Cole's debut album, Inseparable, was released nearly 30 years ago and won two Grammy awards. She went on to have success in the 1980s with hit singles Pink Cadillac and I Miss You Like Crazy.
She has also appeared in acting roles on television, including the made for TV film Always Outnumbered alongside Laurence Fishburne in 1998.
She collaborated with jazz singer Diana Krall on her latest album, Ask a Woman Who Knows - they duetted on a song called Better Than Anything.
Cole cites her famous father as her greatest influence, along with the big jazz stars he exposed her too via his record collection, including Count Basey and Ella Fitzgerald.
She has three tour dates planned for the spring in her home state of California.
