Blue jean babes: Ashton Kutcher and Alessandra Ambrosio get intimate in one of Colcci's new Fall 2011 ads.

Has the fashion industry been Punk'd?

After making a surprise appearance on the runway at Colcci's Sao Paolo Fashion Week show, Ashton Kutcher is starring alongside Alessandra Ambrosio in the Brazilian label's Fall 2011 campaign.

The actor—who got his start as a model for the likes of Calvin Klein—gets back in front of the camera for the racy campaign, in which he appears to be undressing the Victoria's Secret Angel, who replaces former spokesmodel Gisele Bündchen.

Hot and bothered: Alessandra Ambrosio sizzles in leather short-shorts.

While the Colcci campaign also sees the Brazilian-born Ambrosio modeling leather hot pants, Kutcher wears a denim-on-denim ensemble for a sexy poolside shot.

Perhaps next time he can bring Demi along?
