Fashion designer Michael Kors agreed to interview Jessica Simpson for the upcoming issue of style magazine Harper's Bazaar because the actress/singer has become his "muse". Kors admits the busty blonde has had a huge effect on him and he now creates lavish outfits with her in mind. He tells U.S. TV news show Access Hollywood, "Jessica is a great friend and she's kind of a muse. She's the all-American girl but she's got a little edge to her." In the interview, Simpson tells Kors she had to wear "really high heels" when she was dating John Mayer because he was much taller than she was. But that wasn't a problem for Simpson - because the singer lives in designer high heels. Kors explains, "I think she would play basketball in high heels if it was up to her."
