We love former Real Housewives of Atlanta star Kim Zolciak's lovely names for her newly arrived twins, Kane Ren and Kaia Rose. But how did she and husband Kroy Biermann come up with those names? 

Kim gave birth to the twins on November 25, and she kept her love of "K" names alive with the twins' first names — but you might be surprised to learn how Kim chose their middle names.

Kim posted a photo to Instagram on December 4 of the real-life sources for the two middle names. "Our inspiration for the twins' middle names!" Kim captions a split-screen of two photos. "My OBGYN Ren and Rose."

The photo of Kim and Kroy with her OBGYN is at left, and you can see that everyone in the photo has a big smile. Ren has delivered five of Kim's six babies and is quite close with her. Kim also included a separate photo of Rose, who is the psychic whom Kim says is like a grandmother to her.

"It's not often in life you come across people you can truly trust, can always count on, and just simply adore," Kim explains about the middle name choices. "I'm very grateful for these two! ☺️"

Are you surprised by how Kim chose the babies' middle names?
