Kate Upton and Kellan Lutz struck their sulkiest model poses in a new fashion campaign, which was shot on the breezy shores of the bohemian Los Angeles neighbourhood.
The 19-year-old Sports Illustrated swimsuit model diversified from her usual bikini costume by remaining fully clothed in an array of stylish ensembles for the Dylan George and Abbot and Main Autumn-Winter 2012 collection.
She left it to the 'Twilight' hunk to do the flesh-baring, with the 27-year-old actor and model appearing shirtless for most of the behind-the-scenes video.
Lutz, who was recently cast to play Tarzan in an upcoming 3D movie, revealed that he cut out carbs and ate a high-protein diet in preparation for the shoot.
"I try to always stay active and run regularly, but the most important regimen I do to prep for a shoot is my dieting," the Daily Mail quoted Lutz as telling Just Jared.
"Eating the right foods is just as important as working out the right way.
"For this shoot, I cut out carbs a week before and ate a lot of chicken and vegetables three times a day, drank gallons of water each day.
"During the shoot I would drop down and do push-ups and crunches throughout the day to keep the definition needed for each shot," he said.
The actor has worked with the brands before, appearing in campaigns alongside the likes of Victoria's Secret Mode Anne V.
Lutz teamed up with denim specialist and celebrity favourite Dylan George founder Danny Guez in early 2011. (ANI)
