A lot has happened since Kim Zolciak left the Real Housewives of Atlanta and snagged her own show, Don't Be Tardy. A marriage, back-to-back babies, a new house… and if her third pregnancy with hubby Kroy Biermann wasn't shocking enough, Kim surprised us again when she announced that she's expecting twins!

Now the busy mama has taken to Instagram to reveal her ever-growing belly, and we gotta say, pregnancy looks amazing on Kim!

"Going swimming with the kiddos! The pool makes me feel so much lighter! This belly … #twins #excited #blessed#nofilter," Kim gushed.

We love her white-lace-trimmed, black bikini — a strapless number, no less! Aside from her two bundles of joy, it looks like Kim hasn't gained a single ounce of extra weight. Her body looks absolutely flawless!

Of course, Kim is far from the first celeb to show off her baby bump in nothing more than a bikini — though she might be one of the hottest mamas-to-be to date. If you're loving this look and want to compare Kim to some of the other celebrities who've shared their impressive baby bods with the world, don't worry, we've got ya covered.

Another mother to be who's been flaunting her stuff all summer in itty-bitty bathing suits is Pretty Little Liars star Tammin Sursok, who looked an absolute dream in early August. Seriously, most people don't look that hot in a bathing suit, baby bump or not! We're jealous. So, so jealous.

More examples? You got it! Model Gisele didn't let her growing belly stop her from enjoying some time in the sun last year, and she looked picture-perfect out on the beach. Of course, she's a model — she knows how to always look fab. Another model mamma who hasn't let being pregnant slow her down is Elaine Alden, who mastered the art of showing off her growing baby bump in sweet summer style.

In July, Hart of Dixie star Jaime King took a gorgeous black and white bikini shot that deserves to be printed, framed, and hung in her baby's nursery, she looks so good. And all the way back in march, actress Shiri Appleby took the "itty bitty" concept to a whole new level with a look that left little to your imagination.

Still not enough for you? We've got a whole gallery to enjoy! As we said, we think Kim stacks up pretty well against the competition — not that we'd really pit moms-to-be against each other. Honestly, they all look gorg.
