John Legend’s wife, Sports Illustrated model Chrissy Teigen, is slamming Instagram users for commenting on her weight.

Teigen posted photos of herself while at the MTV Upfronts on Wednesday, and she was appalled to see comments on her weight.

“Honestly f--k you all. Why do I even open anything up to you,” she tweeted after seeing the comments. “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. “

She continued, writing “I don't know why I am always surprised when you let me down. I gotta get used to this sh-t.”

Some of the comments included users saying, "You gained weight?" and another saying, "Putting on that weight momma,” E! Online reports.

Teigen is extremely vocal about her life on Twitter, sharing most aspects of it across her social media pages.
