"I got the amazing honor to stand face-to-face with her," said Sparks, dressed in a shimmery black number. "I have amazing memories that I get to cherish. I didn't know her very long. It was two months. It was 12-hours a day for two months. You get really close when you're in that kind of setting. She was so motherly and so kind and hilarious. She was so funny. She would bust out with stories and jokes."
From there Sparks went on to talk about her day-to-day action with Houston. "Every day when she came in she was so happy and so joyous to be there. She would walk in and say, 'How are my babies today? My babies good? God is good!' Every morning she came in like that."
Sparks is set to honor Houston at today's luncheon with a special song tribute.
Sparkle is slated to hit theaters on August 17.
