Braxton Family Values
returns in March for the conclusion of their “most scandalous season yet.”

While the Braxton girls -- GRAMMY-winning singer Toni; Dancing With the Stars alum Tamar; sisters Traci, Towanda, Trina, and their mother Evelyn, a.k.a. "Ms. E” -- have had plenty of drama in five seasons of their reality show, ET’s exclusive look at the second half of season five shows that things are about to be taken to a whole new level.

The supertease spotlights arrests, proposals, custody drama and even social media spats between the sisters -- but it’s a figure from their past that’s bringing the most drama to the family.

Flashbacks from earlier seasons show the Braxton sisters’ tumultuous relationship with their father, Michael Conrad Braxton Sr., who, according to Toni, “forgot about us” when he remarried shortly after divorcing Evelyn.

“I want to plan a trip to Mexico,” Tamar announces, unfazed by sister Trina’s suggestion that “Daddy’s gonna want to bring his wife.”

“She can’t come,” Tamar fires back. “Everybody ain’t invited to the party.”

Invited or not, it seems Michael Sr. and his wife do end up on the Mexico vacation, and, the promo declares, “What the other Mrs. Braxton tells them will change their world forever.”

“You gotta choose your kids!” Tamar tearfully declares over scenes of an emotional family dinner. “It doesn’t matter!”

See the drama unfold in the promo above!
