Kim Zolciak Isn't Coming Back On 'RHOA' But My Kids Are

Kim Zolciak isn't sure why NeNe Leakes is telling people she's coming back to 'Real Housewives of Atlanta' -- 'cause she's definitely not ... TMZ has learned.

Sources close to Kim tell us she has not shot anything for the show, and hasn't signed on to shoot either ... contrary to NeNe's statement.

Kim has her own show on Bravo, and we're told she doesn't see any point in returning to 'RHOA.' Funny enough, our Kim sources say her daughters, Brielle and Ariana, will actually make an appearance next season ... because they went to Sheree Whitfield's son's birthday.
