People magazine cover model Tess Holliday calls herself a “body positive activist,” but not everyone sees her that way. The Los Angeles based beauty, whose real name is Ryann Hoven, has become a global phenomenon as the first size 22 model to sign with major agencies, MiLK Model Management and Bella Model Management, but she’s also faced a harsh backlash.

Simply search Holliday’s name on Twitter and the first words that follow it are “disgusting,” “obese” and “unhealthy.” Not surprisingly, the insults people have hurled at Holliday, 29, are just as offensive.

“Don't like me? DON'T CARE,” the 5 foot, 5 inch stunner tweeted Tuesday. “To the people that fight on my social media: I don't give a f---. Get a therapist, phone a psychic or eat a f---in burger… grow up.” She added: “Never waste your time explaining yourself to people who are committed to misunderstanding you.”

But Holliday wasn’t done there. When a netizen said Wednesday she wished the model would “promote health,” the redhead fired back: “Don’t talk about things you don’t know!!! F--- off.” She also shared a listicle from Buzzfeed about 15 times she “killed it” in the fashion industry.

Holliday has more than 700,000 Instagram followers and 900,000 Facebook fans. She also has a very modern love story, meeting her fiancé Nick Holliday -- whose last name she started using professionally in January -- on Tumblr in 2012. "He pushes me to be a better person, and he believes in me and saw potential in me when other people didn't," she told People magazine about her future spouse. "I feel safe with him." 

The couple plans to wed in a “pretty over-the-top” ceremony this fall. "I already knew I wanted to marry him before I met him," she said. "He appreciated me in a way that no one else had. I think being a feminist himself, he understood what it was like to really appreciate a woman's body -- not in a sexual way, but in that every person is beautiful the way that they are."
