Amy Slaton and Tammy Slaton are feeling the weight of family drama.

In the new trailer for season eight of 1000-lb Sisters, the sibling duo’s once-close bond appeared to be on thin ice as they detailed their ongoing rift.

“It feels like we’re drifting apart,” Tammy, 39, said of her younger sister in a confessional interview. “She used to be my best friend.”

But the pair’s relationship has seemingly shifted significantly. When Tammy’s brother Chris Combs asked her if she and Amy had “stopped fighting yet,” she replied, “If Amy keeps her mouth shut, so would I.”

And the hostile sentiment seems to be mutual. Later in the trailer for the TLC series, Amy, 38, had an explosive reaction after a face-to-face sit-down with Tammy seemingly went south.

“I can’t handle her toxic ass no more,” she said as she dissolved into tears. “I’m done.”

The reality stars’ older sister Misty Wentworth offered insight into the ongoing feud, alleging that Tammy called Amy a “deadbeat mom” to her kids Gage, 5, and Glenn, 3, whom she shares with ex-husband Michael Halterman.
