In TLC’s hit reality series co-produced by The Post, mothers and daughters with little regard for boundaries push their relationship to extremes.

Season 2 of “sMothered,” which airs Sundays at 10 p.m. on TLC, follows three returning pairs from Season 1: Cher and Dawn, who dress alike; Sunhe and Angelica, who share bathwater; and Kathy and Cristina, who live mere houses away from each other — as well as some new pairs.

In case you missed the Season 2 premiere, the episode introduces new Florida-based pair Mary and Brittani, who shower together (yes, Brittani is an adult), and new New York-based pair Marcia and Alena, who wake each other up with face-licking.

It also catches up with Kathy and Cristina, who are still tight and planning for Cristina’s family to move in with Kathy during a home renovation (much to Cristina’s husband’s dismay), and Sunhe and Angelica, who are fighting over Angelica’s fiancé, Jason.

Sunhe disapproves of the fact that Jason isn’t fully divorced from his ex yet, so she’s crashing his dates with Angelica.

Above is an exclusive clip from the second episode of Season 2, which finds Las Vegas-based duo Sunhe and Angelica as they continue to clash over Jason.

“I’m a little irritated,” Angelica says on-screen. “Because I don’t need to stand over Jason’s shoulder to make sure he signs the [divorce] papers. But apparently my mom does.”
