Sister Wives fans suspect Kody Brown’s ‘favorite’ wife Robyn is PREGNANT with his 19th child after social media ‘clues’

SISTER Wives fans are speculating that Kody Brown's "favorite" wife Robyn could be pregnant with his 19th child.

Viewers noticed that the 42-year-old has been quiet on social media for months, leading them to wonder if she's hiding something.

Robyn has not posted on Twitter - where she is normally fairly active - since April.

Fans also noted on a Reddit thread that she appears not to have interacted with Kody's other wives Meri, 51, Christine, 48, and Janelle, 51, in months.

A fan asked: "Is Robyn pregnant? She has been MIA. Meri and Christine are pretty active on social media and it appears they haven’t seen each other."

Another added: "She’s 42 so it’s not far from the realm of possibility. Now would I have a baby at 42? No. Would Robyn? Absolutely."

EXPANDING THE BROOD?

Users also pointed out that Robyn - who is already mom to five kids - talked about wanting another child in the Sister Wives finale in April.

The TLC star - who married Kody in 2014 - told him: "Women talk about that feeling of like, 'Oh, I'm done.' I've never really got that.

"You know when you're young and you're just thinking about having children and people will say, 'How many kids are you going to have?'"

"I would always say, 'Just as many as I'm supposed to have. As many as I've made promises to."

Robyn became emotional before adding, "It is, it's a big deal to me. To make sure, to make sure all my babies are here with me. That's all."

Kody remained neutral on the idea, saying he wanted to “figure out what the right thing to do is and do it.".

Robyn and Kody are parents to son Solomon, nine, and daughter Ariella, four.

Robyn is also mom to Dayton, Aurora and Breanna -- from her first marriage.

Kody has 18 children overall with his four wives, Robyn, Meri, Christine and Janelle. Back in April, he also became a grandfather.

His and Christine's daughter Mykelti has welcomed her first child with husband Tony Padron- a daughter named Avalon Asla.
