The world lost a voice like no other when Whitney Houston passed away. She may be gone but her voice lives on. She recorded one last song just four days before she died, for the movie Sparkle. 'Celebrate' is a duet she performed with co-star Jordin Sparks, written by R. Kelly. The movie will be out in theaters August 17th but you don't have to wait that long to hear Whitney's last song 'Celebrate.'
