Get ready for a crazy new episode of The Real Housewives of Atlanta this coming Sunday, December 29. Titled "Midnight in the Garden of Tea and Shade," the last Atlanta installment of 2013 will include the unimaginable: besties NeNe Leakes and Cynthia Bailey turning on each other! That's right, it's Tall versus Tall this week, when NeNe brings Cynthia to tears.

Here's the episode description from BravoTV:

"With the ladies still enjoying their time in Savannah, things quickly take a left turn when NeNe and Cynthia come to a heated disagreement about parenting, causing Cynthia to have a major breakdown. After attending an outrageous drag show, the ladies enjoy one last home-cooked Savannah dinner together — but an unwelcomed guest creates a huge commotion, causing the meal to end on an unexpected note."

Earlier this season, NeNe and Cynthia revealed their different views on parenting when NeNe felt that Cynthia's daughter, Noelle, was way too young to have a boyfriend. Meanwhile, Cynthia thought that it's better to support Noelle's choice to date by maintaining open communication with her daughter. That way, Noelle is upfront about her love life instead of ending up sneaking around behind her mother's back.

Based on this sneak peek, it seems that NeNe wasn't finished with the topic, though, because Cynthia ends up having to leave the room after breaking down into tears. "I'm not saying you're a bad mom," NeNe insists, as Cynthia excuses herself in a flood of tears.

"NeNe is a little harsh in judging Cynthia," Kandi Burruss tells the camera.

We never thought we'd see NeNe and Cynthia turn against each other!
