Natalie Cole, daughter of famed singer Nat King Cole who scored hits with “This Will Be”, “Our Love” and the timeless cover of her father’s classic “Unforgettable,” died early Friday. She was 65.

According to a TMZ report, Cole passed away from congestive heart failure along with complications from a kidney transplant and Hepatitis C. She had cancelled several upcoming tour dates, including a planned New Year’s Eve show in Los Angeles.

Cole, who publicly discussed her battles with substance abuse, detailed in her autobiography how she overcame those issues to resume her successful career. With over 30 million records sold and numerous Grammy awards, Natalie Cole was one of the bigger voices in music in the 1970s and ’90s. She is survived by her son, Robert Yancy.
