It's hard to believe Kim Zolciak had her twins - daughter Kaia and son Kane - only four months ago, because she looks nothing short of amazing. The former "Real Housewives of Atlanta" star, 35, revealed that she was back in her jeans pretty quickly after the twins were born in late November. "I've been working out with my husband, he kicks my butt," she told ABC News of her workout secrets. Anyone who follows her Twitter, can see that as soon as December, Zolciak was almost back to her pre-pregnancy body.
