"When you a ride or die chick!!!!" NeNe captioned the since-deleted shot. "Hey lil sis, I got your back! Lil sis: yeah ok! Then throws big sis under the bus! What the F--K #loyalty #dontbitethehandthatfeedsyou I'm out #beloyaltosomebody."
Porsha liked the photo and replied, "So you text me and ask me a question then make an assumption. Now you come on social media and blast me! Bitch you got me twisted. #fakeashell #cutthecrap."

We can only imagine the catalyst for NeNe's social media attack was what transpired on Sunday's "RHOA," after Kandi Burruss opened up to her, Cynthia Bailey and Marlo Hampton about all the dirt she had on Porsha's boyfriend, Dennis. NeNe, Cynthia and Marlo all urged Kandi not to say anything to Porsha given their rocky relationship, but NeNe was particularly adamant about Kandi keeping her mouth shut. At the time, NeNe was the closest to Porsha out of everyone in the group.
It turns out that NeNe ran to Porsha immediately after her lunch with Kandi and told her everything. The problem is, NeNe didn't want anyone to know she was the one who filled Porsha in -- but it would appear that Porsha didn't get that memo.
The very next scene showed Porsha in a confessional. "NeNe came to me, and NeNe was like, 'Well, I think she didn't tell you because she was worried about how you'd react,'" she revealed. It didn't seem malicious, so maybe she really didn't know she was supposed to keep that a secret?
Either way, the cat's out of the bag, and NeNe's pissed. It's a shame, too, because the two had just rekindled their relationship at the end of last season.
