Kim Zolciak is ready to pop!

The former "Real Housewives of Atlanta" star put her bare baby bump on display over the weekend -- and it's BIG.

"Sooooo with all the requests I finally decided to post My baby bump today," she posted on Facebook. "The twins will here this month and we are soooo excited and I'm soooo over being pregnant! #countingdownthedays".

The reality TV star is expecting her third child with husband Kroy Biermann. She also has two daughters from a previous relationship.

In another Twitter post, Kim revealed just how big she actually is ... and that she doesn't have a single stretch mark.

"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," she tweeted.

We have a feeling some women would love to know these "tricks" up her sleeve!

Kim's family also celebrated Thanksgiving early the other day, probably since Zolciak's due date interferes with the upcoming holiday. The 35-year-old shared her thanks on Twitter after their meal.
