"There's just no reaction," Sparks said. "I couldn't move. I couldn't breathe. I couldn't say anything. I was in complete shock, and somebody had to sit me down before I fell over. And I just lost it. I lost it completely."

Sparks and Houston's longtime friend Debra Martin Chase, who produced "Sparkle," remembered Houston fondly. Read the full story HERE and tune into "Nightline" TONIGHT to watch the full interviews.

9: 15 a.m. ET: ABC News Political Director Amy Walter takes a closer look at Mitt Romney's choice of Wisconsin Rep. Paul Ryan as his running mate: "In picking Rep. Paul Ryan, whose eponymous budget plan has become synonymous with political polarization, Mitt Romney assured an ideological campaign where a debate over the role of government will be front and center. It is a debate the Obama campaign and partisans on both sides are also eager to have. But it's not a debate that swing voters want. They aren't as interested in choosing whether government should be more active or less. They are more interested in simply having it work." More from Walter's analysis: http://abcn.ws/NkxRk4
