She's rumoured to be pregnant with her first baby with boyfriend Tristan Thompson.
And with fans desperate for the happy news to be confirmed, it seems like Khloe Kardashian's big sisters have gone to great lengths to keep things under wraps.
In a photo of the trio that has been shared on Instagram, Kim, 37, and Kourtney, 38, appear to be shielding Khloe's body from the camera.
With only her head and shoulders clearly visible, both siblings have leaned forward in front of the 33-year-old, who is wearing a flattering black ensemble that could be perfect for hiding a growing bump.
The family snap, which has already had two million likes since it was uploaded, was quick to gather attention from fans who pointed out the "pregnancy cover-up".
"Trying to hide that belly, hey?" one user wrote.
Another said, "Are they trying to hide Ko Ko's baby bump?"
But as one fan pointed out, perhaps the most telling fact is that "Khloe is usually always front and centre with her sisters, but now she's hiding in the back".
Kim, who is having another child with hubby Kanye West via surrogate, however is the only member of the clan to confirm her news.
This unusual snap however, may well have just cemented the gossip as fact.
