Whitney Houston's daughter: 'I can always feel her' March 12, 2012 -- Updated 0219 GMT (1019 HKT) Bobbi Kristina Brown is the late singer's only child She says she can still hear and feel her mother, urging her to carry on Houston, 48, died in her Beverly Hills hotel room last month (CNN) -- Whitney Houston's only child opened up Sunday about memories of her late mother in her first interview since Houston's death last month. Bobbi Kristina Brown, 19, told Oprah Winfrey she can still hear her mother's voice sometimes and feel her spirit, urging her to carry on. She's always with me. I can always feel her," Brown said during the interview that aired on Winfrey's network, OWN. In the same show, Winfrey also spoke to Houston's sister-in-law, Patricia Houston, and her brother, Gary Houston. The famed singer won six Grammys and sold 170 million albums, singles and videos during her career. But in recent years, her accomplishments were overshadowed by her struggles with drug addiction. Houston was married to singer Bobby Brown from 1992 until 2007. Bobbi Kristina was born in 1993. "She wasn't only a mother, she was a best friend," the daughter told Winfrey. She said she was relying on her family, the Lord, and her own mother to pull her through. I'm her daughter. I gotta keep moving. I gotta carry on her legacy ... I still have a voice," she said. Brown was interviewed briefly by Beverly Hills police the day her mother died, but she was too distraught to offer helpful information, sources have said. The grief comes in waves still, Brown told Winfrey, and sometimes it doesn't seem real her mother is gone. I'm getting through it. I'm doing as good as I possibly can," she said. Just trying to keep going.
