As the fourth season finale of WeTV's Braxton Family Values draws near, the network has released an explosive trailer that reveals it is Tamar Braxton vs. the rest of her Braxton sisters once again.

Sisters Blame Tamar Braxton For Feud After Surprise Gone Wrong 'Now It's My Fault?'

The fallout started when Traci, Trina & Towanda Braxton attempted to please Tamar by surprising her on stage during one of her performances.

However, they were not met with the reaction from the Love & War singer that they hoped. Instead she threw a water bottle at Traci before she had one of her assistants ask the sisters to leave the venue.

A clip of the season finale set to air Thursday begins with a dramatic scene. It shows Tamar yelling at her sisters and making it clear that the oldest sister of the clan, Toni Braxton, is not the sole factor when it comes to her success as a solo artist.

She yells, "I have busted my a--. It has nothing to do with Toni Braxton."

But Towanda seems to disagree. She tells cameras, "If it wasn't for Toni Braxton, you wouldn't know who Tamar Braxton was."

Because of the disagreement, and countless others before then, Tamar decides that the sisters should not work together professionally. That would include their highly anticipated gospel album.

At what arguably could not have been a worse time, the father of the Braxton family, Michael, is rushed to the hospital. While it does bring a moment for the sisters to put aside their differences and come together, it is not enough to bury the drama altogether.

Tamar tells her sisters, "I am not happy with the last few months."

Toni then yells, "Why you gotta ruin everything?" while Trina reprimands her for "making a conscious decision to separate herself."

Check out the sneak peek below and tune in to the full episode Thursday at 10/9c on WeTV.
