Kids Can Be So Cruel: Anna Wintour Edition

Front Row, the unauthorized biography of Vogue editor Anna Wintour is hitting the shelves, and there's some choice insight into her dieting history:

Her former best friend Vivienne Lasky recalled how a young Anna would buy her stylish outfits as gifts - but the items were always a size too small. On other occasions, the rail-thin young fashionista would cook all of her pal's favorite meals.
Then, instead of dining with Vivienne, Anna - who would eat a single Granny Smith apple for lunch each day - would watch her chubbier friend eat while deriding her for her weight.

Okay, this helps us better understand the cover of Teen Vogue.
