Heavily pregnant Jessie James Decker shows off her growing baby bump again in loungewear from her brand Kittenish.

In her latest Instagram post, the country star posed in a cream two-piece body suit that consisted of a cropped top and matching bottoms.

The post also features a close-up shot of Jessie wearing the same outfit and another of her in an all-black two-piece as she sits between two other ladies.

These other two models were among the half dozen who posed in various other ensembles from the brand's collection.

Jessie co-founded the casual clothing brand with her husband, former NFL star Eric Decker, in 2014, and it was immediately a hit with customers.

Knowing of previous offerings that sold out quickly, Jessie revealed that with this breakthrough, the company stocked up more, but fans still snapped up everything they had in stock.

'WOW!! This was our biggest @kittenish Basics launch yet!!! We added more quantities than ever before just to make sure everyone could get their hands on them and yet several styles sold out on day one!!!!” she revealed in the caption.

“It makes me so happy that you all love these collections so much that we will be adding them regularly throughout the year.” I don't know what other colors and styles you would like to see below? “Lmk!” she added.

For the cover photo, the soon-to-be mother of four, 35, took a selfie while standing in the middle of what appeared to be a Kittenish store.

With her growing belly taking center stage in the photo with the help of her crop top, the “Comin' Home” singer and songwriter exudes a glow that only an expectant mother can achieve.

Additionally, her brown locks cascade down her back and are partially pulled away from her face at the front, except for a few strands of hair that fall around the frame of her face.

Still wearing the cream two-piece, Jessie gave fans, followers and potential customers a closer look at the crop top and her radiant glow.

In this second picture, she places a hand on the top of her baby bump as she smiles confidently at the camera.
