Porsha is just terrible at lying because she's stupid. You can tell by the look on her face that while she's lying she's thinking "i wonder if anyone is buying this? am i smiling rn?"
On WWHL last night Kandi said she didn't find out that it was actually Phaedra who started the "lesbian" rumor about her hooking up with Shamea, which is annoying to know that she won't confront her about it during the season. Phaedra is getting away with murder her and Kandi and Porsha should both be calling her out.
I haven't seen a single person online who believed anything Porsha said, partly because a) yes, she is thick and b) she does this all the time. She literally just started spewing out anything remotely hurtful and negative she could imagine. You could tell by the look on her face that is wasn't about telling any truths, it was about saying something to hurt Kandi as badly as possible and that was she was getting off on that.
Porsha has quite a dark side. She enjoys emotionally and physically hurting people, and this is something she should really get help for. Maybe the Kordell stuff really damaged her? Kenya is right, Porsha doesn't really take responsibility for this stuff but at some point she'll need to really do it.
It is frustrating knowing we're going to get through the whole season and Kandi isn't going to confront the source of the issue, rather it'll be focused on Porsha on taking all the heat. Kandi has said if she knew, she'd have addressed it with Phaedra but will settle it at the reunion now as she spent most of the filming incorrectly believing Porsha was the real issue. At the very least, it'll make for a great reunion hopefully.
