Sports Illustrated cover girl Chrissy Teigen took to Twitter Thursday to slam Internet bullies who called her fat. The 28-year-old model began her rant by posting a screen-grab of a series of comments made in a picture featured on her Instagram account. In one of the posts, Instagram user amykunchome asks Teiger if she's gained weight. Honestly fuck you all. Why do I even open anything up to you. pic.twitter.com/qW7TjVuIv4— christine teigen (@chrissyteigen) April 25, 2014 "In what other real life situation would you walk up to someone and tell them they're fat or gained weight? Seriously you are POS," Teigen tweeted after posting the image. "I don't know why I am always surprised when you let me down," she continued. "I gotta get used to this [expletive]." After seemingly receiving support messages telling her to ignore the bullies, Teigen continued to stand up for herself. "It's amazing to me that I am told to get over the [expletive] but the [expletive] are never told to stop being pieces of [expletive]," she wrote.
