It looks like Tamar Braxton is to blame for Towanda Braxton's talked about outburst as the sister feud continues well into the fourth season of WeTV's hit series Braxton Family Values.

Towanda and Trina Talk 'Baby' Tamar

Even though the sisters claim to have squashed their drama that took up much of their story lines in the previous episodes, a new sneak peek reveals that that they are still working out their issues.

The short clip looks like it comes just before Towanda's highly talked about blowup in which she throws glasses and almost injures her mom. It's not clear what Tamar and Towanda are arguing about but it's safe to say it's over something Tamar said that Towanda didn't like.

Towanda asked her, "Why did you even make that statement?"

Tamar calmly responded, "You felt guilty because you know how you've been acting...And however, excuse me, let me finish because I let you talk..And then you decided that you wanted to say something. Like you couldn't just let him say something nice about me?"

It's a mystery as to who "him" is, but when Towanda asked if she thinks she has been the same person, Tamar said, "He does."

She added, "Towanda you're not my authority, nor am I afraid of you. So don't talk to me like that, ok?"

The matriarch of the Braxton clan, Ms. Evelyn, chimed in and said, "Every time that we get together, it always ends up this way..."

While the clip ended there, another teaser for the fourth season shows that Towanda got physical in what could have been just moments later. Tamar and Toni aren't sitting in their seats, but Towanda, Trina and Traci are there in what looks like the same scene Tamar and Towanda taped in the previous clip.

Towanda is beating on the table and screaming, "No one cares about me!" before throwing glasses.

Check it out at the :12 mark.
