If you read the comments on YouTube for those videos, it's amazing how many people think she's dumb because of them. Since when does acting silly = being dumb?
She's just goofing off between takes, demonstrating that she's not all aloof like the stereotypical model, yet this somehow inspires a lot of hatred...
Yup, I absolutely agree!
Actually, Heidi made her "Abitur", which is the highest academic school-leaving qualification in Germany. So she's definitely not stupid...
She majored in math and art, if I'm not mistaken, and stayed in school after she won the modeling contest in order to graduate and pass that test. Not the actions of a "dumb model".
