Quinne began acting and modeling on her 6th birthday, appearing on Germany's Next Topmodel, where Heidi Klum surprised her with a cake on the show and sang Happy Birthday to her. By the time she was 10, she'd had spreads in W Magazine, InStyle Magazine, been shot by legendary photographers Peter Lindbergh, Martin Schoeller, and Ellen von Unwerth, and was a regular in Abercrombie Kids ads and store displays.
