Kody Brown’s first three wives had a difficult time when he brought a fourth wife into the family, and Christine Brown emotionally opened up to Robyn Brown dropping the bombshell news that she was jealous when she joined the family!

In the exclusive sneak peek of the upcoming season premiere of Sister Wives obtained by RadarOnline.com, Christine says that she wrongly blamed the new wife and not her husband for the problems.

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."

Think four wives is enough to satisfy all of Sister Wives patriarch Kody Brown's needs? Think again.

In the TLC family's new book, Becoming Sister Wives, Kody admits that neither Meri, Janelle, Robyn nor Christine can truly fulfill all of his cravings.

"To be honest, I'm not sure if any one of my wives could fulfill all of my needs, nor do I believe that I am fulfilling all of theirs," he writes, before going into detail over the specific things that make each of his better halves so special.

Kody Brown is a polygamist with four wives, 17 children, and a soft side that brings him to tears when he talks about his beloved family.

In a Sister Wives exclusive sneak peek obtained by RadarOnline.com, Kody shares how the family has embraced his new wife, Robyn, and their baby Solomon, and he gets choked up as he talks.

The stars of the hit reality show Sister Wives are polygamists, have 17 children and live unconventional lives -- and in an exclusive interview with RadarOnline.com they admit that they’re not like everyone else, in fact, they say: “We are so crazy!”

Kody Brown heads up the family of four wives, Meri, Janelle, Christine and Robyn, and they share with RadarOnline.com what their lives are like as a controversial family in the public eye.

“I think there is a misconception,” Christine says. “We balance our time, we still have kids that do every sport on the planet, and people just don’t get any of that. Just because we are documenting our lives on camera doesn’t mean the cameras are always there.”

Just because they have 17 children to look after between them doesn’t mean Kody Brown and his Sister Wives can’t enjoy a night out.

The polygamist reality star was out in Las Vegas Friday night with three of his wives; Meri, Janelle and Christine.

Fourth wife Robyn seemed to have stayed away from the night out after giving birth six months ago.

Polygamist Kody Brown and his four wives won a recent legal battle against the Utah County prosecutors, allowing their lawsuit to challenge the bigamy law to go forward, RadarOnline.com is reporting.

The stars of the TLC reality show Sister Wives filed a lawsuit against the prosecutors in the town where they lived saying that the bigamy law in the state is unconstitutional.

Polygamist Warren Jeffs, who is behind bars for child rape, is under investigation for preaching to his cult members on Christmas day from behind prison bars, according to officials.

Jeffs, convicted of sexual assault of two girls, ages 12 and 14, who he claims were his “spiritual brides,” is serving a life sentence in a Texas prison and is now being investigated for possibly preaching to his cult members via telephone, which is a violation of prison rules.

"We have confirmed that Jeffs made two phone calls on Christmas Day to a relative," Texas Department of Criminal Justice spokesman Jason Clark told the LA Times. "At this point, we're investigating whether he may have circumvented policy and may have spoken to his congregation."

Even though he is serving a life sentence for child rape, cult leader Warren Jeffs is still controlling his followers from behind bars.

The leader of the Fundamentalist Church of Jesus Christ of Latter-Day Saints has reportedly directed his cult member to continue following his directives in bizarre ways, ordering cult members that men cannot have sex with their wives, that parents must throw away their children’s toys and that teenage girls are not allowed to have cellphones.

He’s written a new book based on “revelations from God” and has sent copies to the members of his breakaway Mormon sect from the Texas prison where he is serving his life sentence.

Trouble is brewing and tensions are growing for the polygamist Brown family, and it is the older kids who aren’t very happy.

In this sneak peek of the upcoming episode of Sister Wives obtained by RadarOnline.com, the teenagers in the Brown family express their anger over having a new sibling.

“I honestly think we already have almost more kids than we can handle,” Hunter says, and his sister Madison seems to agree.
