In high school she discovered a passion for playing basketball, and eventually she joined a club team in Munich. Being 180 cm tall, she was naturally fit for the sport; her classmates even called her "Bean Bar" because of her towering height.
Shortly before her 15th birthday, while celebrating Oktoberfest in her hometown, she was discovered by a talent scout who recognized her potential as a model. Tilla Lindig, a Munich and London based couture label, first booked her. Although planning to study accounting when she left high school, Stegner moved to Paris to pursue modeling afterwards instead.
By the summer 2004, she had done advertisement work for Celine, Yves Saint Laurent, Dolce & Gabbana, Ralph Lauren, and Dior. She also has been the Hugo Boss house model for several seasons. Stegner has appeared in a 2005 campaign for French fashion house Chloé and shows such as Anna Sui, Lanvin, Gucci, Versace and Valentino. She also appeared in the 2005, 2006, 2007 and 2008 Victoria's Secret Fashion Shows.
She also modeled for the 2005 Pirelli Calendar, where she appeared half-nude. Stegner has done print and runway work for the fur industry, wearing fur clothing for American Legend Minks and others.
She has been the face of Aquascutum, Guerlain KissKiss, Hugo Boss Eyewear and the Hugo Boss perfume, and Femme. In 2008, she became a face of Maybelline and Gianfranco Ferré. In 2009 she became the new face of Mercedes Benz advertising.
