Kim Zolciak has two buns growing in her ever-fertile oven, but The Real Housewives of Atlanta star isn’t exactly sure what color to paint her unborn twins’ nursery because she’s still not sure of their respective genders.

The reality starlet’s hubby, Kroy Biermann, made the wigged-out woman wait to find out the sex of the twins until their born.

Some fans thought the stress of not knowing would start to eat at Kimmie, but she took to Twitter to set them straight.

“@elizabethtrivis: @Kimzolciak @JennHobby  aw Kim put your foot down you have to know , lol” it's kinda fun waiting!!!” she revealed.

It is a bit of a surprise. And since Mama Zolciak has already had four children (two of whom were born in the last two years), spicing things up can never hurt.

Kim has said multiple times now that these two will be her last, so hopefully she has at least one girl with Kroy. The 34-year-old beauty had daughters Brielle, 16, and Ariana, 12, in previous relationships, and sons KJ, 2, and Kash, 1, with the Atlanta Falcons football player.

Are you surprised that Kim still doesn’t know the sex of her twins? Tell us below!
