Robyn Brown Is Pregnant

Sister Wives star Robyn Brown revealed the gender of her baby-to-be to the rest of her large family on the Sunday, Nov. 8, episode of the TLC series.

During the show the pregnant reality star eagerly anticipated the revelation of her baby’s gender. “I want you to tell me,” she said to her husband Kody Brown and the ultrasound technician. “We want to know today. Like I’m about to die I want to know so bad.”

The couple who live a polygamous lifestyle along with Kody’s three other wives and their combined 17 children share a son┬átogether.

“The whole family is so excited for our new baby girl,” Robyn tells PEOPLE. “So many of them guessed ahead of time it was a girl.”

It’s been an exciting time for the family who recently revealed the news that Kody legally adopted Robyn’s three children from a previous marriage in June.

“Usually when a plural family goes into a court room they are tearing apart a family so we were really nervous going in,” says Robyn. “But here we were the whole family and we were uniting our family. It was really cool for us. Very much a validation of our family.”
