The cat has been out of the bag since May this year when Bündchen was spotted shooting the campaign on the streets of West London, but we've had to wait until now to see the fruits of her labor.
The model posted a teaser of the campaign on her Instagram account earnlier this week, and now the full campaign has been unveiled featuring the Brazillian star, the world's highest paid model, in a series of cozy winter looks.
It's not her first campaign for the brand, having previously fronted the Spring/Summer 2011 line for the Swedish company.
With campaigns for major luxury labels like Versace and Givenchy, and the face of Pantene in her native Brazil, Gisele last year took home around $45 million in earnings, according to Forbes Magazine's annual survey of the world's highest-paid models.
Dutch supermodel Doutzen Kroes and Beyoncé have also featured in H&M campaigns this year, with the popstar even creating a special music video to show off the brand's swimwear.
