A photo has circulated the internet of Grant Gustin wearing a proto type of the 'Flash' costume.
According to E! News, the photo was said to be taken during a costume fitting.
Many people took to their social media, judging his slim physique in the suit.
Gustin took to his Instagram story to address the comments and the photo itself. The actor wrote;
"So here's the thing about this bulls*** photo leak, It's a cool suit. There's a terrible photo that I was unaware was being taken, much less being posted. Some things need work and they will be worked on. We'll get there.
"As far as the body shaming. That's what pi***s me off... I've had 20+ years of kids and adults telling me or my parents that I was too thin. But there's a double standard where it's OK to talk sh** about a dude's body. I do my best to stay in shape and add as much size as I can throughout these seasons. I'm naturally thin, and my appetite is greatly affected by stress. Stress is something that ebbs and flows for me throughout a season. Thus, gaining weight is a challenge for me."

The Flash star seemed very hurt as he took to Instagram stories with a video to his fans.
