It's been so much fun watching Kim Zolciak's daughters grow up over the last four and a half seasons of The Real Housewives of Atlanta, and see how much closer they've gotten as sisters. It makes us wonder — does Kim have a sis of her own?

Answer: nope! Although she does have an older brother named Michael. Since we've never seen him, we're guessing he's not down with the whole cameras-in-your-face thing.

Did you know that Kim was the only girl in her family?
