It looks like the Brown family will be welcoming a daughter!

The news that Sister Wives star, Robyn Brown, is pregnant with a little girl was revealed on Sunday's episode of the TLC docu-series, and shared by Robyn's husband, Kody, on Twitter.

"It's a GIRL!" he tweeted. "Yippie!"

Robyn, 37, and Kody, 46, are part of a polygamous relationship, in which Kody is "spiritually married" to three other women as well -- Meri, 41, Janelle, 46, and Christine, 43.

Kody had been legally married to Meri, but the two recently got a divorce so that he could marry Robyn, the youngest of his brides.

Between Kody and his four partners, the family has a combined 17 children, and this new addition will make 18.

Kody and Robyn already share one child, 4-year-old son Solomon. She is also the mother three other children -- 15-year-old son Dayton, 13-year-old daughter Aurora and 10-year-old daughter Breanna -- from a previous marriage.
