A recent close-up photo of BLACKPINK’s Jennie has sparked a massive online discussion among Korean netizens, all because of one detail: a faint vertical line down the center of Jennie’s Stomach.
The post titled “What’s that line on Jennie’s stomach?” quickly blew up, racking up over 125,000 views and dozens of heated (and hilarious) comments on Korean forum sites.

Some were genuinely curious: “Is it abs? Or just a bone?”
While others were quick to clap back with facts and personal experiences:
- “It’s something everyone has.”
- “It’s just a naturally skinny body. I gain weight around it, but the center line stays the same LOL.”
- “Ah, People with naturally high muscle mass look like that. My dad and sister have vertical abs. I took after my mom, so I don’t “
- “Even guys get it when they’re skinny.”
- “You must be fat if you don’t have that line…”
- But of course, the internet wouldn’t be the internet without chaos:
- “Everyone post your own pics LOL. Some of you say ‘I’m skinny but don’t have it’, others say ‘I’m chubby but do’ maybe it’s just your fingers being thick LMAO.”
- “Looks like an elementary school kid.”
- “That’s a line God gives to naturally thin people.”
- “I’m super skinny and don’t have that line… just my rib outline. Is that muscle??”
- “Just lose belly fat and you’ll get abs.”
- “It’s not even a muscle zone. If you lose fat and work out a lot, it splits clearly there. It’s not weird, you just never had it before. Go look at anatomy charts before you comment.”
- Others didn’t hold back:
- “C-section.”
- “You posted this hoping someone would say it’s a pregnancy line and now you’re shocked at the backlash, huh? LOL”
- “You fat pig LOL. Of course you’re asking, you’ve never been skinny in your life.”
- “wow…You’re the only one who doesn’t have it.”
- “I’m chubby and I have it too. I guess it’s not just for thin people.”
- There were also comments throwing light shade:
- “She really doesn’t give off that vibe…”
- “Piggy, it’s something everyone has. You’ve just never seen it on yourself.”
- “I’m on the chubby side but I have it too… worked out a lot back in the day.”
- “My skeletal muscle level is below average and I still have that line. It’s not just for skinny girls.”
And then someone just asked the realest question: “Who even is she?”
The verdict? Apparently, the vertical line isn’t some mystical K-pop feature! just something that appears on naturally lean bodies or with the right mix of muscle and body fat.
So, no… Jennie’s not hiding a secret. Just great genes, maybe a strong core, and the whole internet watching her!
