VIDEO : Tess Holliday on Why She Called Out Chloe Grace Moretz for 'Red Shoes' Body Shaming Controve

Tess Holliday says she was horrified when she saw a controversial poster for the upcoming animated film, Red Shoes & the 7 Dwarfs, which compelled her to tweet about it. ET spoke to the 31-year-old plus-size model on Thursday, and she talked about tagging the movie's star, actress Chloe Grace Moretz, in a tweet slamming an advertisement for the film. A billboard for the movie in Cannes, France, shows two women -- one tall and thin, the other shorter and heavier -- and the words, "What if Snow White was no longer beautiful and the 7 dwarfs not so short?"
