Tributes flood in for Whitney Houston Stars of the music industry have been paying their respects to Whitney Houston, who was found dead in her LA hotel room aged 48 on Saturday. Mitch Winehouse, father of the late Amy Winehouse, paid tribute to Houston and the recently deceased Etta James on Twitter, writing: "Amy, Etta, Whitney. Their music will NEVER die. What a great girl group in heaven. Mitch. Cheryl Cole also took to Twitter, simply writing: "So sad:- (" Meanwhile, showbiz journalist Dan Wootton paid tribute to a star with an incredible voice, but powerful demons: "She will be remembered as one of the voices of the 1980s and 1990s. She was a powerhouse, but unfortunately for the last ten years we have witnessed her slow decline. It's something that no one would have expected. There are parallels to the shocking death of Amy Winehouse six months ago. You have to wonder what attracts these incredible voices on a path of self destruction that so often involved drug abuse. Dolly Parton issued a statement through her publicist: "Mine is only one of the millions of hearts broken over the death of Whitney Houston. I will always be grateful and in awe of the wonderful performance she did on my song and I can truly say from the bottom of my heart, Whitney, I will always love you. You will be missed. Music Mogul Simon Cowell said he expected Saturday's Grammy awards to become a tribute to the singer, describing her as a "trailblazer and "legend." He told a radio station: "I'm sure they are going to move quickly and I understand and I expect this is to become, as it should be, a tribute to her because you have to remember a lot of the people who are going to be getting awards at the Grammys, they owe an awful lot of their success, I believe, to Whitney, because Whitney was a trailblazer. It's a night she deserves to be remembered fondly. Whitney made a guest appearance on the British X Factor in 2009 following an invite from Cowell.
