Kourtney Kardashian is bumping along.

The reality star showed her pregnancy progress in an elevator selfie posted via her Instagram Stories Sunday.

In the social media upload, Kardashian, 44, gave a glimpse of her bare belly in a white graphic tee, black leggings and matching combat boots.

The “Kardashians” star completed the casual ensemble with a black floor-length trench coat, as well as black sunglasses on her head.

The Poosh creator captioned the snap with a black heart emoji.

Kardashian announced on June 17 that she is pregnant with her and Travis Barker’s first baby together.

The little one will be her fourth child, as the “Keeping Up With the Kardashians” alum is already the mother of son Mason, 13, daughter Penelope, 10, and son Reign, 8, with ex Scott Disick.

Kardashian and Barker, 47, revealed the sex of their upcoming arrival — a baby boy — at a gender reveal party on June 24.

A Poosh newsletter sent over the weekend detailed the extravagant bash, which came together in under 48 hours.

“She wanted to just have the yummiest food possible and lean into her pregnancy cravings,” the announcement read of Kardashian’s chosen fare.

She opted for “nachos, popcorn, chicken nuggets, corn dogs, hot dogs, sliders, pizza and more” — plus “vegan options of everything” for her husband.

Kardashian and the Blink-182 drummer got married last year in three ceremonies. Prior to their nuptials, the duo began pursuing in vitro fertilization to expand their blended family.

Not only did Kardashian describe her symptoms on her family’s reality show, from weight gain to hot flashes, but she proudly showed off her “IVF body” in bikini snaps in May.

That same month, however, the Lemme creator told “Kardashians” viewers that she and the Grammy nominee were “officially done” trying to conceive that way.

“We would love a baby more than anything, but I just really believe in what God has in store for us,” she explained in the premiere episode. “If that’s a baby, then I believe that it will happen.”

As she and Barker await their first child together, Kourtney continues to make headlines for her feud with Kim Kardashian.

The sisters’ squabble over Kim’s Dolce & Gabbanna collab is playing out on Season 3, with Kourtney accusing her sister of using her “carefully curated” wedding “vibes” for a fashion show.

While Kim admitted that she may have stolen Kourtney’s “thunder,” she ultimately called her sibling a “hater” who “doesn’t have any friends” in last week’s installment.

New episodes of “The Kardashians” air Thursdays on Hulu.
