Zolciak also reveals that she'd "probably" show off her curves in Playboy -- if she gets permission from her kids.
"I'd have to talk to my children, because when you're a mom, it's not just you anymore," she says. "I think Playboy is very classy and sexy, but there's a time and place for it. Kim Kardashian did it very tastefully."
Catch Zolciak on part 2 of 'The Real Housewives of Atlanta" reunion show Thursday on Bravo.
