Image Credit: TLCSister Wives, the new TLC docu-series following polygamist Kody Brown, his three wives (Meri, Janelle, and Christine), and their combined 12 children as they welcome a fourth wife and her three kids, premieres Sunday at 10 p.m. ET. I am already obsessed with the 1 minute 23 second opening. Watch it below. It begins with Kody headbanging at what may or not be his next wedding. Sold! I need to know if he’s as happy as he looks. And where they’re going to put the fourth wife’s “apartment” in the home. (Kody takes you on a tour of their house here.) And if the wives are always as supportive of each other as Christine is of “career mom” Janelle in this clip.
