No mom jeans for Heidi Klum. The mother of three is the sultry star of a new ad campaign for Jordache. The ads, shot by filmmaker Brett Ratner in the penthouse of the Chateau Marmont hotel in Los Angeles, show Klum wearing classic Jordache skinny jeans in dark indigo. In one ad, she is looking over her bare shoulder and brandishing a riding whip, evoking the brand's horse-head logo.

"With her success as a supermodel, businesswoman and mother, Heidi embodies the sexy confidence that the Jordache brand is about," said Liz Berlinger, president of Jordache Enterprises, in a statement Wednesday.

Klum, 34, is the host of Bravo's "Project Runway." She has two sons with her husband, Seal, and a daughter from a previous relationship.

Elizabeth Hurley and Brittany Murphy have also appeared in the ads.
