Aaron Carter shared a photo from hospital after revealing he was body-shamed by a fan. The singer took to his Twitter account Thursday to share a series of messages expressing he was hurt by the incident.

Carter told his more than 600,000 followers on Twitter he is facing medical issues and has an "eating disorder." He also told his fans he was hospitalized and  his appearance was the result of the health problems.

"I'm entirely hurt by a so-called fan that I just encountered. She wasn't realizing I was listening, she said I look like I have cancer. This is body shaming. You guys are bullying me. I've already addressed my medical issues," Carter tweeted Thursday. "I've literally had the hardest week of my life, my dad past [sic] away, my late sister's birthday anniversary was June 6th & people #BodyShame me." 

He later revealed that he was headed to the emergency room "to get a little check up." 

"Lots of shows lately, had to head up to ER just to get a little check up. These shows are crazy lately, gotta make sure I stay strong," he wrote, before sharing pics from his hospital visit. "Been in the hospital three times this month, dealing with health issues and broken fingers, as well as things I can't legally discuss."

When one fan said they were not aware he was facing an eating disorder, Carter replied saying: "That's why people cal me a meth head. And a heroine addict. I promise I'll work on getting bigger physically. I have medical issues I don't want to discuss at this time. #GodBless."

This is not the first time a celebrity was body-shamed by fans online. 

Last year in November, Demi Lovato revealed in an issue of Glamour how she responded to body shamers online.

“If somebody calls me fat, even in a vulnerable moment, I laugh to myself and think, I’m doing everything I can, so there’s nothing I can do about it," she told the magazine at the time. "I don’t have a six-pack. Maybe I don’t even want a six-pack. It doesn’t sound very appealing."

In 2014, Emma Stone spoke in an interview with USA Today about body-shaming: "I firmly believe that nothing really affects you or can really bother you if you don't already feel that way about yourself. I've seen a lot of comments that say, 'Eat a sandwich' or 'She looks sick.' I've been looking at myself in the mirror being mean to myself. I'm not sick. I eat sandwiches. ... In no way is it my intention to be a bad example. That has been kind of bothering me lately. I've shamed myself for it. We shame each other online. We're always too skinny or too fat or too tall or too short. They're just confirming this feeling I have about myself. I'm trying to figure my body out. It bothers me because I care so much about young girls. We're shaming each other and we're shaming ourselves, and it sucks."

Kim Kardashian West was body-shamed and criticized for the weight she gained after her first pregnancy in 2014. Kanye West's wife took to Twitter to slam her haters, saying: "Anyone who has had a baby knows how hard it is to lose weight...your body totally changes! Making fun of me pregnant and making fun of me trying to lose weight now, shame on you. I'm not perfect but I will never conform to your skinny standards sorry!"

Other stars who have been body-shamed include Rihanna, "Modern Family" star Sarah Hyland, Lady Gaga, as well as Amber Rose.
