The Keeping Up With The Kardashians star has kept unusually quiet over the reports, refusing to confirm or deny the claims.
However, she finally showed off a glimpse of her growing ‘baby bump’ as she filmed on Snapchat with sister Kourtney Kardashian.
In a video posted on the mum of three’s account, Tristan Thompson’s girlfriend can be seen flaunting her stomach as she posed in a black crop top.
Khloe isn’t the only member of the famous family to have attracted baby rumours – as it has been widely reported sister Kylie Jenner is also pregnant with her first child.
Fans have been eagerly anticipating confirmation of their baby news, with many demanding answers on social media.
And some have speculated they could finally get answers through the official Christmas card.

Kim Kardashian – who is set to welcome her third child via a surrogate – has been put in charge of the family’s traditional holiday card this year, and has given social media followers daily previews of eagerly anticipated snap.
Her first offering, on December 1, saw son Saint standing amid a stack of Christmas presents.
December 2 saw the 37 year old upload a glimpse of daughter North standing beside Kim, as they prepared for the holidays.
While Reign was the star of Day 3, North was again the centre of attention on the fourth day.
Eagle-eyed fans have become convinced the annual Christmas card will be how ‘pregnant’ Kylie and Khloe announce their ‘baby news’.
Underneath Kim’s latest snap, one wrote: “I hope Kim is the one showing that Kylie and Khloe is preggo (sic).”
“So the Kardashian Christmas Card is that 25 days of Christmas thing,” another replied.
“My theory is on the 25th day it’s gonna be the whole family pic and Kylie and Khloe (or just Kylie) gonna be showing off the baby bumps in the family pic. Bookmark this. Trust the Process!”
