The ads, shot by Patrick Demarchelier, are a twist on the horse-head logo, with the 27-year-old actress posing bareback on a horse in a field. Jordache said the first ads will run in national publications beginning in September.
"We chose Brittany as our model because she epitomizes everything that the updated Jordache brand is about," Liz Berlinger, president of Jordache enterprises, said in a statement Monday. "She is a classic beauty with an individual sense of style. That really comes across when you meet her."
Murphy's screen credits include "8 Mile," "Just Married" and "Sin City."
At the photo shoot in upstate New York, Murphy told Jordache executives that it was the first time she had ridden a horse. After spending the day with Cloud, Murphy said she might take riding lessons when she's done filming her new movie "Love and Other Disasters."
The Jordache Vintage line is available in upscale stores, while the junior label is sold in Wal-Mart.
