SOUR ABOUT KRAUT!

Tension got thicker than over-baked strudel on sexy schnitzel SANDRA BULLOCK's new flick "Premonition" because she and director MENNAN YAPO never stopped yapping in German - which drove leading hunk JULIAN "Nip/Tuck" MCMAHON coocoo!

Whenever the director and German-fluent Sandra "felt like leaving me out of something, they'd talk German," McMahon groused to My Spy. "It became very annoying!" So...vat you did, schatzi? "I goofed on them by slipping into a character I called 'Hitler's Hairdresser' and - in a sorta German accent - I'd start lecturing Hitler about how we needed to cut his mustache shorter, and make it much lighter." Amused, Frau Bullock and Herr Yapo were like: "Das ist gut...now shutt-en zie up, bitte!"
