To be honest, we didn’t even know NeNe Leakes had half-sisters, but apparently she does, and these partial relatives will be playing a big role on Part 2 of The Real Housewives of Atlanta Season 5 Reunion airing this Sunday at 8 p.m. ET.

According to the sneak peek clip below, NeNe comes down on co-star Phaedra Parks for allegedly contacting NeNe’s estranged half-sibs without her knowledge. “There’s some people that try to be low-down and dirty,” NeNe begins. And when Andy asks for specific examples of Phae-Phae’s shady behavior NeNe reveals, “On the first season when I said that I did not know you, what did behind my back was went and talked to my half-sisters, who I haven’t had a relationship with in over eight years.”

Phaedra countered by saying that it was NeNe’s sisters who came to her, but needless to say NeNe wasn’t buying it. “I just had a conversation with my sister and she told me everything that you did. You need to own up to your wrongdoing,” NeNe declared.
