Khloe Kardashian Battles 109-Degree Heatwave In String Bikini

Khloe Kardashian admitted that the September heatwave she endured was "scary," but with a bikini wardrobe, she was doing her best to keep cool. Sharing a sizzling photo on her Instagram last month, the 40-year-old showed hints of her curves in a white top, displaying her toned shoulders as she lay back on a towel. Opting out of a glam photographer's shoot, Khloe took matters into her own hands, snapping a selfie while pouting as she outlined the 109 degrees she'd been battling. Quick to reply was sister Kourtney Kardashian, while eldest sibling Kim Kardashian left a like.

Scroll for the photo. Lifting one arm to her head as she lay on a towel in full sunlight, Khloe modeled a skimpy string bikini top in embellished white fabrics. Showing a little curve as she opted for a low neckline, the reality star sizzled with a cleavage flash, hinting at her abs and accentuating her bosom via multiple diamond necklaces.

Keeping glam in a perspex-rimmed pair of shades, Khloe wore her hair back, and with this heat, she was likely grateful she'd kept her makeup lightweight.

Sporting a discreet layer of dewy foundation, Khloe showed her high cheekbones and full pout, adding a little matte lip stain in pink. In a caption, she wrote: "Hidden Hills Yesterday 109° Today 106°." The mom of two added hashtags of #heatwave #scary and #staysafe.

Gaining over 3,000 likes was 45-year-old sibling Kourtney, who replied: "The hashtags" with a laughing emoji. Meanwhile, family friend and baby daddy to Kourtney, Scott Disick, left a string of fire emoji. Khloe has since made headlines for dropping a new collab with Fabletics and partnering with retailer Amazon while urging fans to start holiday shopping early.

The above photo came as part of a string of Fabletics shots landing on Khloe's Instagram last month. Injecting some glitter into her sporty matching set, the workout queen flaunted her chiseled abs in a strappy bralette and leggings, posing indoors and accessorizing her two-piece with a matching jacket.

"I’ve always been passionate about promoting body positivity and working with a brand that shares those values makes this collaboration so much more meaningful," Khloe told Women's Health last month.

Continuing as she discussed her dealings with the 2013-founded brand, Khloe added: "They understand that people come in all shapes and sizes, and they create pieces that not only fit well but make every person feel confident." April, meanwhile, brought this photo as Khloe straddled a jet ski in a monochrome bikini from her capsule collection with Fabletics. Elsewhere, Khloe continues to promote her Good American brand, founded in 2016.
