The 45-year-old singer hit out at the power couple - who tied the knot in May - for having an ''ill placed'' need for attention and insists the pair don't even realise there are so many bad things going on in the world because they are so self-obsessed.
When asked which celebrity annoys her the most, she said: ''That's a very tough one, but it has to be Kimye.
''They're just one celebrity. They're a thing now so you can't take one without the other. Who could miss their wedding? It was everywhere.
''I mean, if they're in love, that's great. But there's so many other things they could be spending their money on helping the world.
''I feel like their need for attention is just so ill placed today. They don't realise the wars and things going on that they become a little obsessive.''
The 'Stupid Little Things' hitmaker believes the couple - who have 14-month-old daughter North West - would be more likeable if they put their fame to better use.
She added to Gay Times magazine: ''They could serve a better purpose with their fame.
''They would get far more props for doing something like that than I would. But all they seem to care about is themselves.''
