Arriving on a flight from Las Vegas, Sienna Miller was spotted waiting for her limousine outside LAX universal Airport yesterday (April 3).

The “Factory Girl” babe looked cute and casual as she ignored the paparazzi, sporting a black jacket with an ivory scarf by a flowery top with jeans and flats.

Sienna was returning

from the ShoWest 2009 Awards at Sin City’s Paris Hotel and Casino, held earlier that week.

Miss Miller was bestowed the Best Supporting Actress trophy for her work on “The Edge of Love.” Other award-winning celebs at ShoWest included Zac Efron, Audrina Patridge, and Rachel McAdams.
