Kaia Gerber 'Scary Skinny' In String Bikini On Mexico Beach

Kaia Gerber has sparked concern as new photos show her soaking up the sun in Mexico. The model, 24, was spotted in Cabo San Lucas this week, where she spent time with 33-year-old boyfriend Lewis Pullman while showing off her swimsuit body. Looking super-slender in a skimpy bikini as she enjoyed the shorefront lifestyle, Kaia flaunted her mile-long legs and tiny waist, but for some, she's gotten too skinny. Kaia made headlines last year for worrying fans with her slimmed-down physique, with some even suspecting that she's been suffering from an eating disorder. These photos showed the daughter to Cindy Crawford looking happy, but the images still prompted weight-related remarks.

Scroll for the photos. Displaying her long, lean limbs and taut abs, Kaia wowed in a teeny black bikini, going stringy in a halterneck top with triangle cups, plus matching, low-rise bottoms.

Spending time with her older beau, plus friends, the Marc Jacobs fragrance face stunned in the sun, looking leggier than ever as she flashed her curves while chilling out.

Kaia was photographed walking along golden sands with a shirtless Lewis, plus a crowd of pals she'd brought along with her. Going makeup-free, the brunette wore her dark hair down and damp, hinting at a post-swim situation as she padded around barefoot.

The photos were published by Backgrid on Instagram, where fans expressed concern that Kaia was looking yellow. Others, meanwhile, commented on her weight. "Are their livers ok omg," one fan asked, with another asking if Kaia has "hepatite." A third said that the model looked "scary skinny" in one of the photos.

Fans also remarked on Kaia Gerber's weight as The Daily Mail published the photos. Here, one user called Kaia "too thin," with another saying that she has no "muscle tone." Thinking that Kaia's slimmer figure is intentional, one fan gained over 100 upvotes for saying:

"She has starved herself to the body of a 12-year-old. Poor young woman appears to have e body dysphoria." That said, another user defended the starlet, stating: "She is young. Probably just her body type. I was like that until I hit 36. I could eat anything and not put on an ounce."

This fan repost on Instagram had some fans sending Kaia Gerber compliments, but others joined the skinny-shaming. One user called Kaia "skin and bones" as she modeled this barely there minidress teamed with sheer, thigh-high stockings.
