Lili Reinhart was told to "suck in her stomach" by a male director.

The 29-year-old actress - who has been open about her struggles with body dysmorphia - was asked to recall an "acting note that you took personally" during a conversation with her Forbidden Fruits co-stars Victoria Pedretti, Alexandra Shipp and Lola Tung.

In the video for Cosmopolitan, she said: "When I had a male director come up to me and silently lean over and go, 'Just suck in your stomach a little bit.' "

Her castmates were shocked, as Lola joked it was "time for a hex", while they wanted her to name and shame the director in question.

Victoria said: "Oh my God. What is his name? And what is his address?"

Lili - who didn't specify the film or TV show in question - insisted she would tell her co-stars in private after the interview.

Alexandra replied: "Say his name!"

Last year, Lili opened up about the eating disorder she had developed during her time as Betty Cooper on Riverdale.

At the time, she was dealing with unexplained gut issues and weight gain, having being tested for Celiac disease and Crohn's.

Explaining that she'd done "all" the tests, she told Self Magazine: "And my gut's still like, 'Hey, b****, you got something. You just can't figure out what it is.'"

It was around then that Lili - who revealed in December she had been diagnosed with endometriosis - developed the eating disorder.

She recalled: "I really don't like looking at season six imagery or pictures, because I know that 99 percent of my thoughts were about my body.

"I was a thousand percent just disassociated through that entire day or scene because my entire inner dialogue is just… 'Your body's changing.'"

In 2023, Lili called for greater representation of different bodies in mainstream media, and called out the way women were being pushed to have unattainably "skinny arms".

She wrote on X: "I wish there were more average-sized arms represented in mainstream media for women.

"My body dysmorphia has been going crazy because I feel like my arms need to be half the size they are currently.

"We've glamorized these skinny arms that, for most of us, can only be achieved if you're a literal adolescent."
