Under Armour signed supermodel, Gisele Bundchen, to an endorsement deal. Bundchen is the wife of New England quarterback, Tom Brady, who UA signed in 2010.

She's also the the world’s highest earning model, having raked in $47 million this past year, according to Forbes magazine.

On
Tuesday morning, Under Armour posted a teaser video on
YouTube featuring Bundchen. In the video, Bundchen is seen
wearing UA's gear and heading into an empty loft with a heavy bag
hanging from the ceiling. The teaser is captioned: “Under Armour X Gisele Bündchen, Coming Sept. 4, 2014.”

Bundchen is expected to be part of Under Armour's $15 million women's campaign launched earlier this summer with ads featuring American Ballet Theatre soloist Misty Copeland. Besides Copeland, Bundchen joins downhill skier Lindsey Vonn,  pro
tennis player Sloane Stephens, pro soccer player Kelley O’Hara and pro
surfer Brianna Cope in the new “I Will What I Want” campaign.
