On Tuesday's brand-new episode of Teen Mom, Catelynn Lowell and her mother April get into a nasty spat as they argue over household chores and their combative relationship.
Calling Catelynn, 18, a "f***ing a**hole," April quips, "sit in your f*cking room and rot." Catelynn charges that their dynamic soured once she and her fiance Tyler Baltierra decided to place their daughter Carly, 15 months, up for adoption. "You didn't ask me!" her mom says.
Also in this clip, Maci Bookout and her new beau Kyle King play with Bentley, 22 months -- and she makes the momentous decision to move to his adopted hometown in Nashville, Tennessee.
