A new sneak peek of the upcoming Real Housewives of Atlanta shows that Kenya Moore and Phaedra Parks go head to head.

But it surprisingly has nothing to do with the whole 'Sext-gate' ordeal that happened earlier this season between Moore, Parks and her husband Apollo Nida. Instead, the two argued it out about Moore's dog, Velvet, who died at the end of the season after being attacked by the neighbor's dog.

A teary-eyed Moore wiped her face with a tissue and spoke in a crackly voice about why she did not invite Parks, NeNe Leakes or Porsha Williams to the dog's memorial service.

"At that time we had been seeing the show played back and certain things that were said were really below the belt and extremely insensitive, uncalled for and cruel."

Moore used the example of a time when Parks told the cameras that the former Miss USA had "scrambled eggs" because of her inability to have children.

She also called out Leakes and Williams for saying cruel things about her as well. Both ladies made it clear that they don't talk about Moore at all while Parks wanted Moore to tell the whole truth.

Parks said, "But please be clear I did reach out to you and send my condolences about your puppy...I mean, you know, I felt really bad and I reached out to her because as a funeral director I obviously bury animals. I wanted her to know that I was very concerned about her. I knew that Velvet was her friend. That was probably one of her only good friends."

While Parks might have had good intentions in giving her mini speech, Moore thought it was a sly way to throw a little shade.

"Now see that's not fair for you to say that. We know that that's an animal. For you to say that was one of my only friends, that's shade and that's inappropriate at this time. If you wanna say something nice then say something nice. Don't be dirty about my dog."

Parks told Moore she shouldn't be so "sensitive" but Moore just told her to "shut up."

Parks once again referenced the fact that Moore was having trouble having children and said, "Well honey you can't tell me to shut up because you're not my mama...You're no one's mama."
