Kim Kardashian has once again found herself at the centre of fake pregnancy speculation after posting a new snap of her bourgeoning baby bump on Instagram.

The reality star, who is expecting her second child with rapper husband Kanye West, has been basking in the knowledge that she has barely gained barely any weight despite being almost five months along.

On Monday (27 July), the 34-year-old star was seen in a body-hugging white dress with a peach coat while running errands in LA.

Hours later, she posted a selfie of herself in the same outfit but this time her baby bump looked bigger. The image, which shows her cradling her tum and pouting, was captioned: "Good night baby."

For some fans, the different in the appearance of her baby led them to question whether she had enhanced her curves for the purpose of the picture.

Since announcing her baby news, speculation has been rife including suggestions that she is having the baby by surrogate and even parading a fake bump. The rumours prompted the mother-of-one to launch into an expletive-laden tirade on Twitter.

"Can't wait til my website is active! I'm gonna do live video streaming so every time someone talks s*** I can go blast the f*** outta them," she told her 32.3 million followers. "If I got a surrogate I would say I did! Thankfully I didn't have 2." She added: "Pregnant Kiki does not play!!!! *BLOOP*"

Earlier in July, she admitted she secretly loved the never-ending speculation. "I secretly loved the rumors I was faking my pregnancy bc I was so skinny! LOL Well can't hide it now! 5 month (20weeks) and 20lbs up," she told her followers.

Her second child, due in December, will be a little brother to North, who turned two on 15 June.

Good night baby
