Reality TV star Kim, 34, took to Twitter to celebrate the 20 week mark of her pregnancy and to tell fans how her growing tum is coming along...
After being pictured shopping in LA on Thursday (16 July), it was obvious that Kim's baby bump has begun to show...
And now she tells us she's gained at least 20lbs.
In a tweet to her 33.5m followers, Kim also admitted that she enjoyed hearing the untrue rumours that she wasn't really pregnant - because it proved she wasn't showing!
She posted: "I secretly loved the rumours I was faking my pregnancy bc I was so skinny! LOL Well can't hide it now! 5 month (20weeks) and 20lbs up."

In a new photo shared on Instagram this weekend, Kim showed off her new curves - and THAT bust.
Posting a well-lit selfie on Saturday (18 July), she said: "Heading to San Fran for the Horowitz's CEO BBQ! #AirplaneSelfiesHaveTheBestLighting."
In the snap, Kim is showing off some serious cleavage in a black low-cut top.
There's barely a hint of pregnancy tiredness in her face, though, which is looking poutastic!
Kim announced her pregnancy in May and confirmed on US Father's Day that the baby is a boy.
She broke the happy news to fans in a Twitter post praising husband Kanye West for being a fabulous husband and father to their daughter North, two.
Kim confirmed her baby's gender after laughing off rumours including the idea she'd used a surrogate and wasn't really pregnant, and that she was having twins.
She has also been forced to deny rumours she and Kanye planned to call their unborn child South.
Their second child is due in December.
