While Tamar Braxton is known for butting heads with all of her sisters, a new trailer for the upcoming season of Braxton Family Values reveals the new superstar has it out with Toni Braxton several times throughout new episodes, leaving Towanda, Trina and Traci feeling left out.

Tamar Throws Shade on Trina & Gabe's Marriage

In the clip released by WeTV, the sisters finally get to work on their gospel album. But in true Braxton clan form, the divas go head-to-head when it comes to the direction of the project -- mainly Tamar and Toni.

Toni checks Tamar and says, "I'm an old b----, I've been doing this a long time. You're a new artist. I don't wanna be there. I got that."

Towanda Disses Tamar's 'Rude' Fans

Tamar clearly reaches her breaking point because she threatens to drop out of the project because of Toni.

She says in another scene, "That's it for me. And that's why I said I'm not doing that with her. We'll do the album your way Toni... You don't wanna sing with us.

Even though Toni and Tamar can't get along, their sisters aren't too fond of their collective diva attitudes.

Traci tells cameras, "This is like my last chance. Toni and Tamar are acting like they're know-it-alls."

Trina and Towanda have separate issues within themselves. Trina yells, "I am your sister!" while Towanda calmly says, "Trina are you kidding me?"

Towanda also opened up about how she felt when it came to being taken advantage of. She tells Trina, "I became a punching bag. I'm tired of it!"

At the end of the clip, Towanda has her now infamous outburst when she yells, "Nobody cares...About me!"

She knocks over several glasses before walking out as Trina tries to cover her face full of tears.

Braxton Family Values returns on Aug. 14 at 9/8c on WeTV. Check out the extended preview below.
