Actress Sienna Miller's bronzy glow in this picture, taken at at LAX Airport back in 2009, is all natural and likely came from some sort of island vacation -- not makeup!

While we certainly hope that Miller used copious amounts of sunscreen while catching the rays that added some color to her normally peaches-and-cream face, her tanned, slightly shiny visage is all natural and was provided by the sun.

The queen of the boho chic style looks lovely with her effortless pony and sculpted eyebrows.

Once again, a paparazzi-derived airport shot finds a starlet sans makeup. At least Sienna appears to be returning from a little R&R in the sun. She took a cosmetic production vacation and for that, we applaud her.
