Original cast member Zolciak left the show during season five, then returned to stir up the drama on this year's season ten.
Cohen doesn't believe fans should expect to see the flamboyant blonde back again.
As PEOPLE reported, Cohen told E! News recently, when asked about Zolciak on RHOA, "I think she's done, yeah."
Cohen explained that the tension was thick during the season 10 reunion show between Zolciak and co-star NeNe Leakes.
The Bravo exec said, "Kim walked out of that reunion and I said, 'Yeah, I've seen the last of that wig at these reunions.' "
Zolciak, 39, who is married to football player Kroy Biermann, was one of the stars when RHOA debuted in October 2008.
But the feuding was rough on her and she stormed out of a group dinner during season five while pregnant with son Kash (who was later attacked by the family dog).
Zolciak returned to the show this season to tangle with Leakes once again – this time, there was trash talk concerning roaches!
The reality queen, who was spun off into her own show, Don't Be Tardy, which continues to air, told PEOPLE, "RHOA can be very combative. A lot of negativity. I just was extremely frustrated…I had had enough."
But Kim fans won't be cheated if she does end her time on RHOA once again--the seventh season of Tardy is expected to premiere this summer.
