I don't know much about German supermodel Franziska Knuppe but she is our Saturday Siren for this weekend for a very valid reason. She's extremely hot! Exactly, that's all we need to crown her our hot babe for this Saturday. If you want some more evidence regarding her eligibility for this honor, then here are some sizzling hot photos from the Triumph Lingerie 2010 Christmas catalog right after the jump. Welcome to CelebGuru, Franziska!
