"I can hear her voice and her spirit talking to me telling me, keep moving, baby. I can always feel her with me," she said. "She humbles me. I remember what she told me, I remember what she taught me. ... She was a sister, a comforter. The spirit that she had -- no matter where she was ... she touched everyone."

She revealed fairly extensive plans to follow in her mother's footsteps.

"We are going to do the singing thing, the acting thing, the dancing thing. It's a lot of pressure, but she prepared me for it," she said.
