The Sister Wives clan is getting its first grandbaby! Maddie Brown is pregnant and expecting her first child with husband Caleb Brush, TLC confirms to Us Weekly.

“So happy to announce our little addition!! 💙,” Maddie captioned a sweet photo of Brush kissing her pregnant belly on Instagram on Monday, November 21.

Their happy news comes just months after Us exclusively revealed the pair said “I do” in an intimate outdoor wedding ceremony this past June in Bozeman, Montana, where her whole family was in attendance. The duo got engaged in September. 

The reality star is the daughter of Sister Wives stars Kody and Janelle Brown. Kody is married to four women; they have a total of 17 kids.

“We think it would be super cute to have different names for all the grandmas, like Oma, Grams or Babicka,” Maddie told People while discussing her pregnancy. “'Grandma' said differently or in different languages. Ultimately they get to choose what they are called, but my dad [Kody] will probably be Grandpa.”

Sister Wives airs on TLC on Sundays at 8 p.m. ET.
