Supermodel Kate Upton is once again showing off those curves in a new sultry photo shoot for Redemption Choppers' Spring/Summer 2013 campaign, the Daily Mail reports.

The 21-year-old poses in the Namibian dessert in a deep V-neck dress, braless in a tight leather jacket and staring intensely into the camera while wearing a long-sleeve knitted shirt. The blonde beauty teased fans with the photo shoot back in June by posting a picture from the shoot on her Twitter page with the captain "I want to go back to Namibia... So amazing there!"

Redemptions Choppers is an Italian clothing brand that caters to "custom-made motorcycles  and design biker-chic clothing for both men and women," the Daily Mail reports.

Supermodel Isabeli Fontana also joined Upton for the shoot. The young model caused temperatures to rise back in June after posing nude on a horse. TMZ was able to get their hands on an uncensored video that was apparently shot two years ago, putting the model at 19-years-old.

The celebrity website reportedly took the video down but not before generating a ton of buzz. There have been no reports whether the model responded to the video but she has gone on the record in the past saying that she is extremely comfortable in her body.

"The things that they're rejecting are things that I can't change. I can't change my bra size.... They're natural! I can work out ad I can stay healthy and motivated, but I can't change some things," the Inquisitr reports. "I really just live my life. I love my body, it's what God gave me! I feel confident with myself, and if that inspires other women to feel confident with their bodies, great."  

The model has been keeping busy filming the movie "The Other Woman" with Cameron Diaz and Leslie Mann. The comedy is directed by Nick Cassavetes and centers around a woman who finds out her boyfriend has been messing around with other women.

"The Other Woman" is scheduled to hit theaters April 25 next year.
