Brittany Murphy Channels Jessica Simpson in Music Video  4/21/06

Sin City star Brittany Murphy stunned cast and crew members during a music video shoot for her debut single by showing up looking exactly like Jessica Simpson.

The actress shows off her singing skills in British DJ Paul Oakenfold's new track Faster Kill Pusycat and appeared in the rooftop promo, which was filmed in Los Angeles last weekend (15APR06).

The Just Married star had a logical explanation for her striking resemblance to Simpson - she hired the pop star's hairstylist and best friend Ken Paves to help her with her look for the shoot.

Paves used blonde extensions from the range he's launching with Simpson later this year (05) to create Murphy's hairstyle.
