'Real Housewives of Atlanta' Star Kim Zolciak -- I'm Getting My Own Reality Show!!!

Ain't no thing that "Real Housewives of Atlanta" star Kim Zolciak was missing from the new season 5 promo shots ... because TMZ has learned KZ is getting her very own spin-off show!!!

In case you missed it ... RHOA debuted their new ads recently and noticeably missing from the group was KZ  -- which birthed monstrous speculation that the housewife had been axed from the fifth season (below).

But sources close to the production tell TMZ that KZ will DEFINITELY be in season 5, but only sparingly.

We're told Kim was pregnant during production and producers made accommodations to feature her in the show on a limited basis. Our sources say she was ready to pop when the promos were shot ... ergo her absence.

But Kim's not too beat up about the lack of screen time. We're told her short-term series, "Don't Be Tardy For the Wedding" -- which aired on Bravo earlier this year -- was a ratings hit, so producers decided to give KZ a full-time spinoff of her own, which is already filming in GA.
