The reality TV star showed off her rounded tattooed tummy in an Instagram photo, revealing that she is four weeks away from giving birth.
Rob Kardashian's fiancée has previously claimed it is her goal to "gain like 100 pounds this pregnancy", the equivalent of seven stone.

"Like, no lie, my goal is to gain 100 lbs. this pregnancy," she said on Snapchat. "I'm gonna tear it up, and then I'm gonna snap back."
In the lead-up to the birth, Chyna has been sharing photos of her growing bump. "Can't wait to meet my baby girl #Scorpio #32weeks," she wrote alongside a close-up photo of her stomach.
Chyna, 28, and her fiancé Rob, 29, chose to announce their baby's gender during the premiere of their new reality TV show Rob and Chyna.

As they head off to the doctor for the big reveal, Rob says: "I'm pretty nervous, I'm excited. I really want a boy."
"You're having a girl!" the doctor then tells the parents-to-be. "Rob, it's a girl!" Chyna repeats.
Initially Rob seems a little taken aback by the news, but soon becomes emotional at the prospect of having a daughter.

"Me wanting to have a boy stems from my relationship with my dad," Rob later explains on camera. "I'm just happy that the baby's healthy and I am super happy I am having a girl."
This will be the first child for Rob and Chyna. The pregnant star has a four-year-old son King Cairo Stevenson with her ex-fiancé Tyga, who is now dating Rob's half-sister Kylie Jenner.
