The 33-year-old is already mum to one-year-old North, her daughter with rapper/random phrase generator Kanye West, but a chance comment in an interview on Tuesday (28 October) seemed to hint at a possible new addition to the clan.
The slip-up came while the reality TV star and notable booty-haver was asked about her maternity style by Sam and Nic Chapman, the sisterly duo behind Youtube make-up channel pixiwoo.
Kim's (possible) reveal comes at around the 2.30 mark:
"I wore my regular clothes and tried to... I just would buy a size up," Kim explained, before either letting the cat out of the bag or making a simple slip of the tongue, depending on how you choose to interpret her next comment.
"I don't know if I would necessarily do that this time around," Kim begins, before appearing to become flustered suddenly, stopping short and finally stammering: "I don't think... I mean..." and changing the subject to her favourite maternity clothing store.
Has she realised she's said too much? In any case, she seemed to get away with it - Sam and Nic were clearly too transfixed by Kim's flawless barnet to notice the potential gossip bombshell in their midst.
Lucky for Kim - Jeremy Paxman would have been on her like stink on cheese!
Once she'd successfully steered the conversation back into the general concept of maternity fashion, Kim seemed back in her element. "Pregnancy style is hard," she confessed. "I'm not gonna lie." Even harder, of course, when dozens of baying paps are following you the moment you leave the house.
