The 35-year-old beauty is infuriated by comparisons between the supermodel and Jude Law's girlfriend, insisting Miller is nothing more than a cheap caricature of the catwalk queen.
She says, "A lot of people compare the actress Sienna Miller to her.
"But I can't stand to hear that. I don't know Sienna Miller but there is no comparison to Kate. I don't like imitations, I like the real thing."
