Britta Heidemann posed for German Playboy in 2004
As the earlier Korean report said, German fencer Britta Heidemann—a.k.a. the One who Robbed Shin A-lam–did in fact pose for German Playboy in 2004 (NSFW).
Feel free to Google for more photos on your own.
If it makes Shin feel any better, Heidemann lost in the gold medal match.
