KIM Kardashian has sparked concern after her bikini top appeared to slide off her shrinking frame in a new TikTok video.
The mother-of-four tipped back a shot while appearing in Kylie's friend Yris Palmer's TikTok.
As Kim held the shot in one hand and a glass of fruit juice in the other, her top barely stayed in place.
Fans couldn't help but share their concern on Reddit, with one writing: "Okay she's actually tiny," while another added: "Seriously, how she doing this?"
She recently hit back at critics of her weight loss, insisting she has dropped the weight in a "healthy way."
"But I had a nutritionist, I had a trainer. I have never drunk more water in my life.

"I don’t see the criticism for other people when they lost weight for roles — they are [considered] geniuses for their craft.”
Back in May, Kim revealed the measures she took to drop so much weight.
And in June, the Keeping Up With the Kardashians alum admitted she has lost even more weight after sticking to the ultra-strict diet.
She said on The TODAY show: "It actually taught me a lot about my lifestyle and my health, and since then, afterward, I continued to eat really healthy.
"I mean, I'm down 21 pounds now. I'm not trying to lose any more weight, but I have more energy than ever."
FEARS FOR KIM
“Kim looks amazing, always, but she’s good at keeping how stressed she is hidden,” an insider told The U.S. Sun.
“She's the skinniest she's ever been and barely sleeping. Her family knows that a lot of this is her rebounding from a very controlling marriage, and her determination to show Kanye how much better she is doing without him.
“But whereas before she was incredibly healthy and well-rested, now she's constantly jetlagged and she’s finding it hard to fit workouts in. I think Kim’s really struggling but won't admit it.
"She is having a great time with Pete but the travel is taking its toll and she’s barely sleeping. Everyone is worried she’s burnt-out.”
