NARS has posted a behind-the-scenes video of the photo shoot for the beauty brand's Fall/Holiday 2010 campaign starring heiress Daphne Guinness. The two-minute clip was posted on NARS' YouTube channel on October 25.

The video features short interviews with NARS founder and creative director François Nars, NARS makeup artist Kabuki, and Guinness, who was the inspiration behind this season's collection.

For the campaign, Guinness wears products from NARS' Fall/Holiday 2010 line including a rich royal purple in Daphne - the shade was named after her ($23), a yellow-green eye shadow in Mangrove ($23), Douceur blush in soft pink-brown ($26) and Rouge Basque Lipstick, a red hue inspired by the French Basque region ($24).

Guinness, a socialite and longtime friend of François Nars', replaces Marcel, Nars's dog, as the new face of the cosmetics line.
