Sienna's Hot and Spotted in the City

Sienna Miller had no problem rockin the knee-high boots despite the NY summertime heat yesterday. Fashionable yes, but this look certainly couldn't have been comfortable. The actress was in NYC to promote Interview earlier this month and she has another film, Stardust hitting theaters next month. We're curious what it's like to work with Sienna, but if you have any other questions for the Stardust director, let Buzz know before her interview. Her movie career is on the rise, but there's another exciting reason why Sienna is in NYC. She is debuting the fashion line she designed with her sister, Twenty8Twelve, tonight in Manhattan! Last month we got a peek at the Sisters' line, but we can't wait to see the whole thing.
