Whitney Houston was reportedly planning to remarry Bobby Brown in Las Vegas.
The 48-year-old singer - whose body was discovered in the bath of her Beverly Hills hotel suite on February 11 - had apparently wanted to reunite with her former husband of 14 years and the pair had decided on an intimate ceremony with their daughter Bobbi Kristina, 19, as the only witness.
Author Derrick Handspike - who wrote Bobby's biography - told the National Enquirer: "Bobby told me, ' Whitney and me are getting married again.'
"They were planning a small wedding, probably in Las Vegas with just the two of them and their daughter Krissi. Bobby told me, 'The world may have thought we were history, but the reality is we were never really apart. We've never stopped loving each other.'
"After his dad's funeral in Boston in December he flew to Atlanta. For the next week Bobby holed up at Whitney's home, where they rekindled their romance and their intimate relationship. They slept together in Whitney's bedroom and talked about what kind of wedding they'd have."
Bobby is also said to have told Derrick that he believes he could have prevented his former spouse's untimely death.
He added: "Bobby told me 'I could have saved her! If I had been with Whitney, she never would have died in that hotel bathtub. I would never have left her alone."
Although Bobby is thought to be engaged to Alicia Etheredge, mother of his two-year-old son Cassius, Derrick claims the pair split last November because of his love for Whitney and says Whitney's feelings for toy-boy lover Ray J had turned to friendship.
He said: "While Bobby takes parental responsibility for Cassius, and remains friends with her, Alicia realised Whitney was the love of Bobby's life. It was almost as if Bobby was still with Whitney and Alicia was the other woman.
"Bobby knew Whitney was still in love with him. Even Ray J knew nothing could break Bobby and Whitney's tight bond. Their relationship had turned into more of a friendship."
