Chloe Grace Moretz has always been a proponent of body positivity, but she claims she was subjected to some severe body shaming due to her size a few years ago.

The 20-year-old actress, whose upcoming animated film “Red Shoes and the Seven Dwarfs,” is set to be released in theaters this summer, revealed to Variety that a male co-star once called her “too big” to be girlfriend material after she was embroiled in a controversy over an ad that implied weight gain would make Snow White less beautiful.

Moretz told the source that the man in issue was “23, 24 or 25” at the time, when she was still in her mid-teens, and that the encounter was “jarring.”

She said: “This guy that was my love interest was like, ‘I’d never date you in real life,’ and I was like, ‘what?’. And he was like, ‘yeah, you’re too big for me’ – as in my size.

“It was one of the only actors that ever made me cry on set.”

She didn’t say who the actor was, but she did say she was 15 at the time and that the conversation was “really, really dark.”

“I had to pick it up and go back on set and pretend he was a love interest, and it was really hard. It just makes you realize that there are some really bad people out there and for some reason, he felt the need to say that to me,” she explained. “You have to kind of forgive and not forget really, but it was just like wow. It was jarring. I look back on it and I was 15, which is really, really dark.”

Moretz also revealed that a male co-star tried to undermine her by circulating false stories about her on set. “I’ve had a younger male lead ostracize me and bring up fake issues just to try and put me in my place, and make things up to the director: things that are crazy, things that I would never do, unprofessional things that would make no sense,” she explained. “I’ve had an actor do that to me. It’s crazy. They have this inferiority issue, and I’m like, ‘You are completely equal to me, you are no different than me. I just happen to be the lead in this movie, and I don’t know why, just because you are kind of the smaller character, that you’re pushing me into a corner to try and put me down.'”

Moretz also addressed the challenges of being a woman in the entertainment industry.

“I deal with it every day,” she said. “You’ve got to stick to your guns. I always say, ‘Get me in the room and make me audition, and I’ll try and win it and at least I’ll know then that I did my best and I gave my all’, but if you just look at me and you say no, then I don’t know what to tell you. But when one door closes, another one opens, and that’s the way it is so don’t fight it. I never try and push myself on someone who doesn’t want me for the role.”

Moretz previously admitted to feeling “insecure” about her weight while filming the 2013 adaptation of Carrie.

“I felt fat; I felt not pretty. I felt like I didn’t really know who I was,” she told Marie Claire.

“I was so confused; I was scared. I had bad acne. I felt incredibly insecure.”
