As Life & Style exclusively reported, three out of the four wives on TLC's hit series Sister Wives are threatening to quit the show after their husband, Kody Brown, discussed the possibility of bringing in two new women.

The 48-year-old "has zero source of income" without the show, family friend Kendra Pollard shares, and with 18 kids to feed, he can't risk losing that paycheck.
