Whitney's daughter: 'I can hear her, I always feel her'

Whitney Houston's family have opened up to Oprah Winfrey about their loss in a television interview which aired in America on Sunday.

For the first time Whitney's sister-in-law Patricia Houston and her daughter Bobbi Kristina spoke about the singer's death.

19-year-old Bobbi told the talk show host she was "doing okay ... I'm doing as good as I possibly can," since her mother was found lifeless in the bathtub of her room at the Beverly Hills Hilton hotel on February 11, the eve of the music industry's Grammy Awards.

"I can hear her voice, you know, and spirit talking to me, telling me, you know, 'keep moving baby. I'm right here. I got you' ... she's always with me. I can always feel her," Bobbi Kristina Brown told Winfrey.

The interview, which took place at the Atlanta home of Houston's brother Gary and sister-in-law and manager Patricia, revealed new details of the day the singer died.

Oprah opened the broadcast by saying "members of the family told me she (Houston) was face down and naked" in the bathtub, and Patricia revealed that Houston's assistant, Mary, discovered the singer's body in the hotel room bathtub.

A security guard who is Patricia Houston's brother tried in vain to resuscitate Houston in the room but was unsuccessful.

Winfrey asked Patricia Houston if she believed drugs were involved in the singer's death. Patricia Houston said she believed the pop star's worse days of drug abuse were behind her, although she stopped short of saying Houston was not on drugs or drinking on the day of she died.

"I don't think drugs (were) an issue for her before her death. I don't know what happened that day. Do you understand what I'm saying," Patricia Houston said.

Whitney's friend and hairdresser Tiffany Dixon spoke to Daybreak about the interview she said she believed Bobbi Kristina was coping "well" for someone so young.
