'Riverdale' Star Charles Melton Apologizes for 'Immature, Offensive and Inappropriate' Fat-Shaming Tweets

"Riverdale" star Charles Melton's past looks to be coming back to haunt him.

Melton, who plays Riverdale High's jock Reggie Mantle on the CW hit, is now being accused by fans on Twitter of fat-shaming women, as controversial tweets from 2011 and 2012 have resurfaced.

The actor -- who was around 20 or 21 when the tweets were apparently written -- didn't start acting professionally until 2014 and gained notoriety after being cast as Reggie in 2017 (following Ross Butler's exit at the close of Season 1.)

Some of the disturbing tweets -- which fans believe belonged to Melton -- included fat-shaming women, but also fat-shaming kids.

"Fat chicks need to understand that wearing yoga pants is a privilege, not a right," one tweet attributed to Melton stated.

"Word of wisdom for the day...if your (sic) fat...don't look in the mirror," another said.

While yet another offensive tweet read: "don't tease fat kids, they already have enough on their plates."

The tweets were screenshot by a Twitter user, before Melton appeared to have deleted all tweets before 2014 following recent media coverage.

TooFab has reached out to Melton's reps for comment.

Fans, of course, were extremely angry with the apparent discovery of the comments.

Meanwhile, both of his costars (and "Riverdale's") leading ladies Camila Mendes and Lili Reinhart have been very vocal on their social media platforms about body-acceptance. Mendes works with Project HEAL, a nonprofit organization that provides funding for eating disorder treatment.

"I'm done believing in the idea that there's a thinner, happier version of me on the other side of all the tireless effort," she wrote on Instagram. "Your body type is subject to genetics, and while eating nutrient-dense foods and exercising regularly will make you healthier, it will not necessarily make you thinner, and the current system fails to make that distinction. I'm sick of the toxic narrative that the media consistently feeds us: that being thin is the ideal body type."

Reinhart has always been open her body, health, and acne. Last month, in fact, she responded to pregnancy rumors on her Instagram, clapping back at the haters (and fat-shamers!)

"This is just my body," she wrote. "And sometimes I'm bloated. Sometimes an unflattering photo is taken of me. Sometimes I go through periods of time where I gain weight. My body is something that I will NEVER apologize for. My body will constantly go through change. And so will yours. And that's fine. So let's not put so much time and effort into caring about a stranger's figure."

Users on Twitter went off on Melton as the alleged posts made the rounds on the internet. Read on for some reactions.
