"I feel like I'm just getting fatter," Kim Zolciak told Life & Style in April. "He thinks I'm sexy ... He makes me feel beautiful."
Zolciak has been linked to Biermann since the summer of 2010 and announced in November that she is pregnant.

"I really want 2 know the 'confirmed source' that has seen the ring that Kroy 'supposedly' gave me," Zolciak wrote on her Twitter page. "I am dying to know what it looks like IDIOT."
Zolciak rose to fame on "The Real Housewives of Atlanta" and in 2009, released her debut single, "Tardy for the Party."
