Of course there's going to be some jealousy when you're not the only woman in your husband's life.
This Sunday, TLC will be airing the Sister Wives' Tell-All Special, and our exclusive clip addresses one issue that was illustrated this season: Meri stealing Christine's thunder by getting pregnant.
How dare she!
For the first time on camera, Christine openly addresses the issue and admits she told Meri not to get pregnant. But Christine also mentions that she felt horrible about the whole ordeal afterward.
NBC News' Natalie Morales also talks to Kody Brown and the women about polygamy, life in Las Vegas and their new book Becoming Sister Wives, which details life in the Brown family before the cameras started rolling.
The special airs on TLC this Sunday at 10 p.m.
