Whelp, we've seen the last of Kim Zolciak's bare baby bump photos — at least for now.

The "Real Housewives of Atlanta" alum, 35, has given birth to twins, she announced on Monday morning.

"Guess what?!!! The twins have arrived," she wrote in a message posted on Instagram. "We welcomed first a baby GIRL and second a handsome little BOY! They are both healthy and Kroy and I are so thankful!!"

As for names, yes, the "Tardy for the Party" singer and her NFL player husband Kroy Biermann, 28, opted for ones starting with "K" again. (The couple, who married in 2011, already have sons Kroy, 2, and Kash, 1, and are raising her daughters from previous relationships — Brielle, 16, and Ariana, 12 — whom Biermann adopted.) However, who the newborns have to thank for their names is where things get even more interesting.

Their daughter will go by Kaia Rose. Zolciak explained that the middle name is a tribute to … her psychic. "Psychic Rose," who has appeared on "Housewives" to offer Zolciak spiritual guidance, is "like a grandma to me" and "a huge part of my life for 13 plus yrs," the new mom wrote. The twins were born on Rose's birthday.

 As for their little boy, he's Kane Ren. His middle name pays homage to … Zolciak's ob-gyn, "who has delivered 5 of [my] 6 kiddos" and has been "a big part of my life of 12 years," she shared.

Zolciak added, "We are officially the 'Biermann Bunch' now!"

Talk about a busy household! Despite having her hands full, Zolciak was a busy Instagramer throughout her pregnancy, routinely sharing photos of her growing pregnancy belly with her 350,000 followers. The most recent bare belly pic was posted on Nov. 17 and showed her looking ready to pop.

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

The wig-loving blonde also routinely tweeted updates about her condition, including a brag or two.

"Hubby just measured my belly OMG!!! 48 inches around!! And not ONE stretch mark!!" she tweeted the same day. "I know stretch marks r genetics but I have some tricks!"

Well, the countdown is over. The babies are here. And we offer our congrats to the new — though very experienced — mom.
