1000-Lb Sisters is back! And so is the drama... In a new trailer, Amy and Tammy Slaton's brother Chris Combs drops the news it's been about "two months since Tammy and Amy had their big blow up" fight. Oof! Throughout the video, tensions are high between the Slaton sisters, who don't seem to be on speaking terms right now. There's a lot of avoidance and frustration. At one point, Tammy sadly says: "It feels like we're drifting apart. She used to be my best friend." Related: Tammy Engaged To GF Just TWO MONTHS After Going Social Media Official!
