KOURTNEY Kardashian has narrowly avoided a wardrobe malfunction in a new TikTok as she shows off sexy white lingerie.

The Keeping Up With the Kardashians alum has been parading her curvy figure in revealing outfits despite rampant pregnancy rumors.

Now Kourtney, 43, has flaunted her cleavage in a sexy new video shared on her TikTok profile.

The reality star modeled a lacy white teddy with no bra underneath as she got her hair and makeup styled by her team.

The TV personality pursed her lips at the camera with a sultry expression, before switching shots to show various throwback pictures from her teenage years.

Kourtney was just centimeters from a wardrobe malfunction as she filmed herself in the racy attire.

The Poosh founder has been sharing thirst trap photos on social media, flaunting her curvy figure despite fan pregnancy rumors.

Earlier this week, she gave her viewers a glimpse of her bare stomach in a new video.

The reality star randomly decided to do a handstand up against a wall.

While wearing striped silk pajamas, Kourt successfully performed the maneuver, while her shirt slid up exposing her bra underneath.

Fans couldn't help but notice her bare stomach looking for any clue that she might be with child.

Her handstand video came as the reality star's husband seemingly dropped a major clue on his social media about a potential pregnancy.

The Blink-182 rocker took to his Instagram Stories to proudly show off a mug with a telling message.

The brown cup had "Greatest dad of all time" written on it.

Travis, 46, added a tiny man emoji to the photo, placing the person on the rim of the glass.

The musician is already father to teens Landon and Alabama Barker, both of whom he shares with ex-wife Shanna Moakler.

Kourtney, meanwhile, has three kids of her own.

She shares her son Mason, daughter Penelope, and youngest child Reign with her ex Scott Disick.

While she and Travis have been trying for a baby of their own for some time, they have faced several setbacks on the journey.

Much of the process was documented in season one of The Kardashians.

Despite documenting their struggles, fans have become convinced that Kourtney and her man are secretly expecting.

Kourtney recently tried to squash pregnancy rumors in a recent mirror selfie shared on her Instagram feed.

Amid a series of photos from her trip to London with her hubby Travis Barker, 46, in one snap the reality star showed off her bare belly.

It appeared flat and toned despite speculation she could be pregnant.

In another photo, the Hulu star indulged in french fries and bread rolls, breaking her diet while on vacation.

Fans were also convinced that the Poosh founder was hiding something in a promo pic for The Kardashians season two.

In the glitzy shot, Kendall Jenner, Khloé, momager Kris, Kim, and Kylie Jenner all posed in black on a nude angular sofa while Kourtney stood furthest in the back.

Not only that, but she seemed to strategically hide her tummy area behind Kylie in the shoot.

She also wore a frilly, loose-fitting dress while her sisters all wore form-fitting, tight outfits.
