Here Today, Gone Tomorrow! Kim Kardashian's Bump Disappears While She Tapes KUWTK With Her Sisters

It’s the case of the mysterious baby bump! Kim Kardashian is pregnant, we think, but it was definitely hard to tell as she and her sisters headed to Hugo’s restaurant in California to film scenes for their reality show.

Dressed in all grey everything, Kim looked dashing (get it?) in a long dress and sheer overcoat. She completed the look with laced-up black heels and shades.

Days prior, when she was wearing a tight white dress, her pregnancy bump was finally visible, but bam, just like that, it’s gone again!

While she struggled with her maternity style while pregnant with North and even admitted to still wearing clothes she still would’ve worn had she not been pregnant, it looks like Kim has really learned from her past fashion don’ts.

“I do think that tighter works a little bit better and is a little more slimming,” she recently told DailyMail. “And I don’t care how hot it is, I’m going to wear like thin coats all summer. Like light, thin airy coats to kind of conceal my bigger arms…I’m going to have a strategy of just really simple this time.”
