The Sister Wives along with husband, Kody Brown, were on Oprah today. The hot topic of the day? Jealousy. Oprah is pretty suspicious about this multiple wives thing. Watch as Oprah probes the cast about jealousy, double standards and more.

When Kody kisses latest wife (and then girlfriend) Robyn before they're married, Janelle expresses anger turning to Kory and saying: "So, next time you get married make sure your next kiss isn't front of the other wife." Oprah's response? This is weird.

Later in the program, Oprah asks the wives about the double standard regarding polygamy. While the wives acknowledge the double standard exists, they power through it- despite their obvious jealousy- because of the Mormon faith.
