"I secretly loved the rumors I was faking my pregnancy bc I was so skinny! LOL Well can't hide it now! 5 month (20weeks) and 20lbs up," Kim tweeted, reports aceshowbiz.com.
The rumours emerged earlier in her pregnancy because she didn't "look pregnant" except for her growing baby bump.
The 34-year-old, however, never hides her curves as she keeps wearing bodycon dresses in various outings.
