Khloe, 38, took to her Instagram feed on Wednesday to share a sultry photo with her 309million followers.

In the snap, the reality star posed on the beach while facing away from the camera.

The TV personality slyly looked over her right shoulder as she grabbed her right butt cheek.

Khloe’s long blonde hair was styled in messy beach waves and she sported full glam makeup for the shot.

The mother of two looked insanely fit, flaunting toned arms and her perky butt in her skimpy gold bikini.

The Good American founder’s rear end looked smaller than ever before as she boasted her incredible weight loss over the past several years.

The Hulu star has been promoting her latest swimwear collection with her clothing company.

The standout swimsuit is a part of their newest collab with the swim-based brand, Body Glove.

Fans were given a glimpse into the collab that featured many different styles of swimsuits in various colors.

The Good American x Body Glove collab will be available on June 15.

In other recent Good American photos, Khloe was photographed swimming in a crystal clear pool while rocking a bright pink bikini.

The star’s barely-there bikini bottoms showed off most of her backside, which has noticeably gotten smaller.

Over on her Instagram Stories, Khloe continued to promote the new collab while showing off her brand new look that made her almost unrecognizable.

KEEPING UP WITH KHLOE

Earlier this week, Khloe showed off her six-pack abs in a new photo posted to social media.

The blonde took to her Instagram Stories on Friday night to share a special birthday tribute to her friend Savas Olguz.

The reality star posed next to her buddy, wearing a teeny tiny pink crop top and matching leggings, paired with pastel Nikes.

The Kardashian sister flaunted her tanned skin and toned tummy in the snap, showing off her wavy blonde locks and full glam makeup.

Khloe stood next to Savas, who sported a white T-shirt, white jeans, white Nike sneakers, a mint-green sweatshirt, and a New York Yankees baseball hat.

The mother of two captioned her post: “Happy birthday @worldwidesavas!!! You know you have a special place in my heart.”

The Good American founder looked thinner than ever in the shocking snap as she flaunted her incredible weight loss.

FAMILY CONCERNS

Khloe’s big sister Kim has shared their family’s concern over her weight loss in the past.

“You look very skinny,” she told Khloe during a season two episode of The Kardashians on Hulu.

“Not that I’m trying to out them but Kendall and Kylie did say that they were a little concerned for you because you look really skinny and I said I think she’s a bit stressed.”

Khloe struggled to suppress a grin and said: “And Kendall said it? The model? Wow.”

Kim went on: “I said, ‘No guys, it’s fine.’ I said, ‘You absolutely have every right to be concerned but I’m telling you, she’s fine’.”

Khloe appeared to celebrate her sisters’ concern, lifting her leg into the air and doing a little dance.
