Red Velvet’s Seulgi Slammed For “Weight Gain” During Fan Interaction
Red Velvet’s Seulgi recently opened up to fans during a casual chat on Bubble, but what she expected to be a lighthearted update quickly turned uncomfortable.

A simple message about her new running routine led to comments that many fans now say crossed the line.
Seulgi got online to share that she had taken up running, a trend many idols have been trying out this year. She joked about treating herself to a beer afterward, but this harmless detail prompted a few fans to respond with scathing and shocking criticism.
One fan questioned why she would drink beer after exercising, and another bluntly told her that she had “gained a lot of weight lately.”
Rather than reacting with frustration, Seulgi handled the remarks with her usual honesty. She admitted she had put on weight and mentioned she wanted to lose a couple of kilograms.

Fan: “No, but you really did gain a lot of weight lately.”
Seulgi: “Yeah, that’s actually true… I need to lose about 2 kilos…”
She then explained that the change happened after a recent trip. According to her messages, her sleep schedule became irregular, her digestion was off, and the overall shift in routine made it harder to stay consistent.

What might have stayed a small moment on Bubble soon grew into a heated debate after it reached international fans. Fans on X (formerly Twitter) criticized the tone of the messages Seulgi received, calling them insensitive and unnecessary.

Many expressed disbelief that paying subscribers would use the platform to comment harshly on her appearance.
bbl really makes some of you think that you can say whatever just because you’re paying for it, you are talking to REAL people! https://t.co/NmzaLeKMFy
