She told Oprah that Whitney had actually called her the day before to say she loved her and was going to come visit her. She says she had no idea it would be the last time she would talk to her daughter.

In her book, Remembering Whitney, she writes that she was devastated when her son, Gary, called to tell her on February 11 that Whitney had passed and even now says she remembers little of that day. "I was alone," she said. "I was a wreck, I was just a wreck."

In the book, Cissy writes of Whitney's decline and how she staged an intervention for her. "I went down there, and did what I had to do," she explained.

In 2009, Whitney talked about this intervention with Oprah saying Cissy gave her an ultimatum: go to rehab or retire from music.

In the Oprah interview from four years ago, Whitney also talked about her troubled marriage with husband, Bobby Brown, who Cissy says she knew was bad news from the beginning. She also explained that she wanted to help Whitney get out of the marriage sooner, but "she wasn't ready to get out."
