TLC 'Sister Wives' Dad Kody to Be Father for 17th Time

He and his wife are expecting a baby in October.

Kody Brown's family is expanding ... again.

Brown — the 43-year-old patriarch of the polygamous family featured on TLC's Sister Wives — and his fourth wife, Robyn, are expecting a baby.
"You should have seen the look on his face when we found out," Robyn tells "It was priceless."
The baby, due in mid October, will be the first for Kody and Robyn, who has three children from a previous marriage.
This will be the 17th child for the family, which includes Kody's three other wives and their kids.
Says Kody, "I'm overjoyed. This connects Robyn and I together in a way that nobody can take away."
