Simon Cowell and Quincy Jones Tribute Whitney Houston

Amy Winehouse's father Mitch said he was "absolutely devastated" and tweeted: "Amy, Etta, Whitney. Their music will NEVER die. What a great girl group in heaven. Mitch."

Producer Quincy Jones released a statement saying, "I am absolutely heartbroken at the news of Whitney's passing. I always regretted not having had the opportunity to work with her. She was a true original and a talent beyond compare. I will miss her terribly. There are so few people like her in the world. They are a rarefied breed, these are true superstar, legendary divas and I say divas in the nicest possible way. She had one of the greatest voices I have ever heard in my life, ever."
