Brazilian Supermodels -- SOOOOO SADDDD ... After German Ass-kicking

Not even a diamond-crusted wonderbra could make Brazilian supermodels Adriana Lima and Alessandra Ambrosio happy after their team got SMACKED AROUND by zee Germans yesterday.

Instead, Adriana looked like she was fighting back tears ... like most of the Brazil fans who were at the game ... and Alessandra was so mad, she flashed a duck-faced thumbs down to the paps!!!

Meanwhile, over at Heidi Klum's pad ...
