If you've been wondering exactly how big Kim Zolciak's belly is, now that she's due to give birth to her twins any minute, we have great news for you! Her devoted hubby, Kroy Biermann, took a moment to break out the measuring tape and get an accurate reading on that double bump. You won't believe the results!

The former Real Housewife of Atlanta took to Twitter to share Kroy's measurement.

"Hubby just measured my belly OMG!!! 48 inches around!! And not ONE stretch mark!! I know stretch marks r genetics but I have some tricks!" Kim exclaimed.

Her fans were so enthralled with the high number that they begged to see an updated photo of Kim's belly. Kim finally gave in to her followers' demands.

"Sooooo with all the request I finally decided to post My baby bump today! The twins will here this month and we are soooo excited and I'm soooo over being pregnant! #countingdownthedays," Kim wrote next to two photos of her full-grown belly.

We're not sure why Kim was reluctant to post recent pictures — she looks absolutely amazing! Yes, her belly is huge, but this mama is all belly. Kimmie looks like she hasn't gained a single ounce anywhere else on her body.

As for her comment regarding stretch marks, the mama of almost-six plans on sharing the wealth!

"I'm going to put a blog up on http://kimzolciak.com  this week on how to prevent stretch marks!" Kim promised.
