Cheers! Bini's sister throws a glass of wine in Ari's face in 90 Day Fiancé sneak peek

If Bravo is looking to start up a Real Housewives of Ethiopia edition, the casting directors should look no further than this week's episode of 90 Day Fiancé, because it features a reality wine-tossing moment that is one for the history books.

In the exclusive sneak preview above, Biniyam ("Bini") breaks the news to his family that he is permanently moving from Ethiopia to New Jersey with his fiancée Ariela ("Ari") and their son Avi — the very next day. Not surprisingly, his two sisters, Mimi and Wish, don't take the news well.

"If you thought about us as a family, maybe a heads up would have been nice!" says Wish in the clip. "Both you and her knew all this time and kept it secret. It sucks."

Ari makes it clear to her sisters-in-law-to-be that their brother is the one who wanted to keep the big move secret.

"Him not telling you guys has nothing to do with me. It's nothing to do with me at all!" Ari exclaims, as she urges a silent Bini (who can't even make eye contact with his sisters) to tell Mimi and Wish the truth. "I would never tell him never not to tell his family, that would be so f---ed up on so many levels. I would never do that."

But Mimi and Wish don't trust Ari, and blame her for this situation. "I don't care whose fault it is, but if you think you are family, you should tell us," says Wish. "He should tell us too. We treat you like a sister."

That's debatable.

"You don't treat me like a sister!" retorts Ari. "If that's how you treat your sister, I want nothing to do with it."

Ari takes things one step too far when she adds, "I'm happy that I'm not going to see you guys anymore. And you know what? I'm not going to marry you guys. I'm marrying Biniyam." At that, Wish angrily throws a glass of red wine in Ari's face before storming off.

"Oh my God, I've never gotten alcohol thrown in my face before," says a stunned — and soaked — Ari. "That's a new experience."

We're guessing Mimi and Wish won't be needing to buy bridesmaid dresses.

Check out the preview above, and watch more 90 Day Fiancé drama unfold this Sunday at 8 p.m. ET/PT on TLC.
