Heard some odd things about Kate Bush recently. Seemingly she is trying to block a public right of way and a beach in Devon, where she has a second home, and is so obsessed with her privacy she even went up in a helicopter to see if people were looking into her garden. Also she seems to go ballistic if anyone catches a glimpse of her in garden in her main home.
However, the singer usually is kind to her closest friends and perfectly fine with fans at occasional conventions. It's just she can't stand anyone near her private world.
