I don't think Nene is jealous of Kim, I think that Nene still has the "Tardy for the Party" bug up her butt. She put the curse of death on that song ("That song will be nothing without me on it") and to see that the song did well and led to another song and a mini tour, well it just burns her biscuits!! Not that she wants to tour and play pop star, it's just that she is left with egg on her face that the failure she predicted and wished for didn't happen. As a matter of fact, it did better than anyone dared to dream. It's a hard pill for her to swallow, and hopefully this last argument will finally help her to gulp it on down!
Nene still cracks me up sometimes, but she is really her own worse enemy. She cannot deal with not being in control. There is still hope for her. Hopefully it is something she will be able to address one day, after all, we are all a work in progress.
