Music star and actress Whitney Houston has died aged 48.
The American singer best known for monster hits such as I Will Always Love You and How Will I Know had previously appeared on The X Factor in 2009 singing new song 'Million Dollar Bill' as well as mentoring acts who included Joe McElderry and Stacey Soloman.
Houston had also been recently touted as a possible replacement for axed X Factor USA judges Nicole Scherzinger and Paula Abdul after a shake-up saw show boss Simon Cowell get rid of both female judges on the American talent show.
The music mogul took to Twitter this morning to say: "I am so sad to hear about Whitney. We have lost one of the greatest singers of all time."
Whitney battled her addiction to drugs in the 90's and in recent years was better known for her trouble with drugs than for her music but she had been turning her life around with news of a tour as well as a film remake of Sparkle which Houston was set to produce and star in alongside American Idol winner Jordin Sparks.
However, today, her publicist confirmed reports that Whitney has died aged 48. The cause of death has not yet been revealed.
