Kim Kardashian& Haylie Duff battled it out on MySpace.
On May 3, 2007, the lesser Duff sister shared a bulletin on her profile titled “Kim Kardashian Is Really Mature”:

Inside, Haylie wrote:
“Stuff like this REALLY PISSES ME OFF. I try to reach out and be nice and instead it just gets shoved back in my face. This is why you should never move to Hollywood, the place is full of arrogant, immature, and offensive bitches who can’t hold their liquor and can’t keep their legs closed.”
And attached screenshots of the heated exchange:


While the Duffs & Kardashians had previously been friends, Kim’s then-keeper Paris Hilton was not too fond of the Duff duo. In 2004, Paris & Haylie both recorded demos of the song Screwed, which Haylie intended as the first single from her debut album… but later scrapped it when Paris’ version leaked online.

To add salt to the wound, the following year rumors swirled that Paris had shoved Haylie’s little sister Hilary on a red carpet, which Hilary didn’t exactly deny.

But despite her newfound bad blood with Paris’ protege, Haylie’s friendship with Kim’s stepbrother Brody didn’t sour!

Happy 10 Years!
