"My son [Michael Houston called me and he was screaming, 'Mom, Mommy. Oh god,'" she said of the phone call she received Feb. 11, 2012. "I said, 'What's wrong?' He said, 'Nippy. Nippy,'" using the family's nickname for Whitney.
"I said, 'Is she dead?' And he said, 'Yeah, Mommy, she's dead' . . . And I don't remember too much else after that."
