With one dad, four moms and 17 kids in Kody Brown's polygamist household, personalities are bound to clash, and in the TLC family's new book Becoming Sister Wives, Janelle shares a fiery exchange which saw fellow wife Christine walk off the show's set.

"When Kody let slip that he had selected Robyn's wedding dress himself, Christine was devastated and walked off set," Janelle writes. "The show has to fit into an hour of television, so the necessary edits make it look as if she returned immediately."
