Kendall Jenner strips down to just white bra and short shorts as she sprawls out in the bathtub

SUPERMODEL Kendall Jenner has stripped down into a tiny white bra to promote a line of oral care products.

The Kardashians star shared an image from the risque pH๏τo shoot on her Instagram Story hours before she turned 28 years old.

Her 28th birthday was on Friday.

The reality star simply wrote: “@moon,” and tagged the company she was promoting.

In the pH๏τo, Kendall was sitting on a tile floor in a bathroom.

She was holding a black toothbrush and looking off to the side with her mouth partially open.

The Hulu star showcased her statuesque frame in the cozy-looking white bra and a pair of white shorts.

The model left her long brunette locks in a tousled loose style and sported a glowing beauty look for the pH๏τo.

Kendall has had a business relationship with Moon for quite some time.

She’s even co-created a few of her own oral care products for the brand.

The post comes in the wake of growing speculation that Kendall’s older sister Kourtney Kardashian has given birth to a baby boy.

Several Kardashian family members, including Kourtney’s husband, Blink-182 musician Travis Barker, have been spotted arriving at Cedars Sinai Hospital in Los Angeles on Thursday, per TMZ.

Kourtney has three kids with her ex Scott Disick: Mason, Penelope, and Reign.

This will be her first child with her rocker husband, Travis.
