The good news broke out on the reality show "Sister Wives." Maddie Brown is expecting her first baby with her hubby Caleb Brush. They can't wait to welcome a new member in their family, and Maddie even took to Twitter to announce the good news:

The news become viral after Brush posted the tweet wit the pic of her wife's bump. He said that every new parent is anxious, but they have full support from their family members. Maddie is the eldest daughter or Kody and Janelle Brown. Maddie's father practices polygamy as he has three other wives besides Janelle; Robyn, Meri, and Christine.

Pregnancy is a good news for every family. However, for this reality show, it is not just an announcement. It is also a rumor. According to Radar, the baby's father, Caleb, is still considered Maddie's relative.

How? Here is the explanation: Kody's brother, Curtis, is married to Erica Brush and had a family. Unfortunately, Kody's brother died in a fatal motorcycle accident in 2013. Erica has a brother, Caleb, who is Maddie's husband. In simple words, Caleb is Maddie's uncle, but not by blood.

The baby is expected to be due in May. And it is very interesting how this baby will have four grandmas. Brown think that it would be cute for the baby to have different names to call the grandmas.

The couple got marriage in an intimate outdoor ceremony in Bozeman, Montana, in June after the engagement in 2015.

Sister Wives is a reality show depicting the life of a polygamist family which is rarely seen. The show is about Kody Brown with his four wives and 17 children settle the differences and have a"normal"life like other families. The series are aired on TLC.

Congrats Maddie and Caleb! Wish you all the best!
