According to People, Robyn Brown, one of Kody Brown’s four wives, is pregnant with the couple’s first child.

“You should have seen the look on his face when we found out,” Robyn says about Kody’s reaction to the news. “It was priceless.”

This will be the 17th child for the unconventional family. It’s also the fourth baby for Robyn, who has three children from a previous marriage.

“I’m overjoyed,” Kody, 43, told People magazine. “This connects Robyn and me together in a way that nobody can take away.”

Robyn also revealed that the rest of the family has been very attentive to her and she is considering home birth.

Baby no.17 is due in October.

The reality show is about the life of a fundamentalist Mormon family in Nevada. Kody is also married to Janelle, Christine, and Meri, who is his only legal wife.
