Despite what fans have described as a thinning frame, KHLOE KARDASHIAN has turned her attention to her famous backside.

In social media images posted on Friday, the 37-year-old reality star showed off her booty while working out in just a bra and tight leggings.

Khloe took to Instagram Story first thing in the morning to share a photo of herself working out at the gym.

She showed off her tiny figure in high-waisted pink leggings and a light pink sports bra, and she completed the look with pink sneakers.

Khloe confidently posed with one hand on her hip and flashed her famous booty to the camera.

Despite her intense workout, the mother-of-one wore her long hair down.

She revealed that the workout began at 5:58 a.m., captioning the photo, “Rise and shine.”

The TV personality posted the photo after fans expressed concern about her recent weight loss.

Khloe shared a video of herself looking thin in a blue sports bra and matching leggings on her Instagram Story earlier this week.

LOVE CHILD SCANDAL

Khloe has been working out at the gym since Tristan and Maralee gave birth to their son Theo together.

Following weeks of denial, the NBA star admitted he was Theo’s father and apologised publicly to Khloe in January.

Khloe and Tristan have a three-year-old daughter True, and the athlete also has a five-year-old son Prince with ex Jordan Craig.
