When proud polygamist Kody Brown, of the TLC reality series 'Sister Wives,' married his fourth wife back in May, both newlyweds had their hands full: Kody, 43, was already the father of 13 children with his first three wives, while Robyn, 31, was a single mother of three.

Now, news is breaking this weekend that a 17th child is on the way. That's right, Robyn (pictured at far right) is expecting her first baby with Kody.

"You should have seen the look on his face when we found out," Robyn told People.com. "It was priceless."
