We all know Chanel's bagged a brand new mademoiselle -- Blake Lively -- and now it's time to see the brand's newest face in action.

The "Gossip Girl" star fronts the campaign for the French house's new range of Mademoiselle handbags. Shot by Karl Lagerfeld, the first image from the ad campaign, now out in weekly and monthly magazines, sees the blond beauty pressed up against a mirror, clad in a black feathered Chanel top with a red patent Mademoiselle bag slung over her shoulder.

Ooh la la!

Karl's new muse has nothing but the utmost admiration for the designer -- she even whipped out her cell phone post-Chanel shoot to capture an image of Lagerfeld behind the camera, according to WWD.

Despite her numerous appearances on the red carpet, in fashion magazines and her super-close proximity to the drool-worthy wardrobe of her alter ego, Serena van der Woodsen, don't expect to see Lively designing any time soon.

"I have such a respect for fashion and such an appreciation for it that if there are people like Karl Lagerfeld out there designing, who am I? I want to bow down to them and be a representative for them if they'll have me," she tells WWD.

Look out for Lively in her next role on the big screen, opposite Ryan Reynolds in this June's "Green Lantern," where she sheds her Park Avenue wardrobe in favor of business suits and fighter-pilot apparel.
