“You know, in all honesty, I think she had a heart attack, that’s what I think happened to her,” Dionne told " Entertainment Tonight."
Last month a Los Angeles County coroner official downplayed the suspicion that drugs had played a major role in her death. Warwick shared her thoughts on drugs playing a role in Whitney’s death, saying, "I don't know if it's that or not. I think her heart just gave out."
Warwick tells Entertainment Tonight she accompanied Whitney’s body when it was flown from Los Angeles to New Jersey, and she also planned Whitney’s funeral. Warwick says she had to put on a brave face during the funeral because Whitney’s mother and daughter were in the front row breaking down.
As for Bobbi Kristina’s first interview since her mother’s death, Warwick says she was “absolutely wonderful.” She says she was asked to participate in the interview, but wasn’t ready for it.
