Well, we don't know that drugs played a part in her death yet, do we? Sadly, plenty of people die of natural causes in their forties.
I was just thinking of the concept of 'rest in peace' when it comes to Whitney. I reckon there's no chance of anyone in heaven resting peacefully for a while with her belting out 'AND I-E-I-E-I WILL ALWAYS LOVE YOU-OU-OU-OU-OUWILLALWAYS LOVE YOU....'
Still, even though I didn't like her much, she will be a huge loss to many.
RIP
