If you don’t want to know the sex of Sister Wives star Robyn Brown’s baby, you better look away.

Robyn Brown is having a girl!

Brown, whose polygamous lifestyle is the focus of the TLC series, revealed the big news to People.

“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.”

This week’s episode of Sister Wives will show Robyn and husband Kody receiving the news.

It is so fun getting kisses on my belly from Truely and Solomon everyday! They like to yell "Hi baby! I love you!" so the baby can hear.
