Singer and actress Jordin Sparks has opened up about what it was like to work with vocal icon Whitney Houston on their film, 'Sparkle'.

It was Houston's final movie project before her untimely death back in February, but Sparks explained that it was an incredible opportunity and she developed a great relationship with her that was "nurturing":

"It was the scariest thing I’ve ever done and I never performed that song before in a concert, so I remember being on stage being ready to walk out and hearing her going, ‘You got this, you got this'. She put my head in her hands and looked at me and said, ‘You’re everything that we wanted'."

“To have your idol tell you that — that was the type of woman she was. She was so nurturing and wanted to see everybody else succeed. She just wanted to see us do well.”

When asked about her reaction to the tragic news that the 'I Will Always Love You' superstar had died, Sparks admitted that she was left feeling as though she couldn't breathe:

"I lost all feeling. I couldn’t move, I couldn’t say anything. I don’t think I was breathing. I still have moments where it hits me and it’s like, she’s not here, there’s this void."
