Ashton Kutcher Colcci Ads Pair TV Star With Alessandra Ambrosio (PHOTOS)

No matter how many times he poses or walks down the runway, we still can't wrap our minds around Ashton Kutcher as a fashion model.

The jokey "Two And A Half Men" star, who actually began his career as a model, has formed a close relationship with Colcci, the Brazilian fashion brand for which he's walked not one but two runway shows. He's also posed in Colcci ad campaigns, including these July spots, with pal Alessandra Ambrosio.

Last month at Sao Paulo Fashion Week, Ambrosio walked the Colcci runway (while pregnant!) as Kutcher cheered on from the front row. But now he's back to work, posing for Colcci's Fall/Winter 2012 campaign (Brazil's got reverse seasons).

For the ad, newly-single Ashton gets cozy with Alessandra on a bed, bravely donning double-denim while the Victoria's Secret model gets to wear some sexy print minidress. While we're not certain when the ads were shot (perhaps when Ashton was in Brazil last month?), there's a good chance Ambrosio was already pregnant when posing with Ashton... in which case, damn girl. That's one teeny tiny baby bump.

Check out the improbable pairing of Ashton and Alessandra below, as well as shots from the most recent Colcci runway. Do you, like us, have a hard time seeing goofy Kelso as a fashion campaign star?
