If there was ever a living advert for staying away from drugs it is Whitney Houston.
Arguably one of the greatest female talents of our generation, the years of drug taking has left her a pale imitation of the great vocalist she once was.
Her appearance on X Factor this weekend was shaky at best by her own high standards and the interview afterwards was painful to watch.
She looked confused, took an eternity to answer the questions the host, Dermot O'Leary, asked and shuffled uncomfortably while staring at the ground.
It could be excused as a sign of nerves, after all she is returning to the stage after almost a decade away but with her history you have to think that it goes much deeper than that.
I don't know if she needs the money or if she has other reasons behind her comeback, but if this is an example of what we can expect from her, she would be best advised to cancel it now before she turns into the Elvis of our generation and is remembered more for the humiliating struggle at the tail end of their careers rather than their heyday.
Something else this weekends X Factor showed was that you could see why Cheryl Cole was not so keen to sing live. And she has the nerve to criticise anyone else about their singing?
