First we reveal Kylie Jenner's baby bump for the first time, now Khloe's!

Since half the Kardashian-Jenner clan is pregnant -- or has someone pregnant for them, in Kim's case -- there's just no end to the interest in these ladies' bellies. In fact, we found it interesting that, Monday night at the studio following a taping session for Keeping Up With the Kardashians, Kim flaunted her NON-pregnant abs in a sports bra, sweats and button-down.

Meanwhile, Khloe wore a blousey black top and skinny jeans -- skinny jeans that weren't so skinny. And again, people, we're not fat-shaming here; Khloe's body is obviously beautiful and on-point, it's just a little more voluptuous than usual so despite her not having made an official announcement that she's pregnant, we think these pix speak for themselves.

Kourtney recycled the same outfit she wore on a date with boyfriend Younes Bendjima this weekend at Nobu -- but flared jeans and a black V-neck top. For once, she's the only one NOT pregnant!
