In some leaked campaign pictures, the 41-year-old model could be spotted wearing only a pair of black lace undergarment, reported Ace Showbiz.
In one photo, Klum is lying on the bed while covering her modesty with both hands. She flashes a cheeky grin at the camera as her hair is messily styled around her face.
Another shot shows the "Project Runway" host and judge lying on her side while showing off her long legs.
Back in October, it was announced that Klum teamed up with Australian lingerie brand Bendon to launch Heidi Klum Intimates in January 2015.
