Fans have been delighted by the news that Kody and Robyn Brown from Sister Wives are expecting their second baby together and the 18th overall in the family, and now, thanks to one of the other wives, details may have been revealed about the sex of the incoming baby!

Robyn Is Pregnant!

Robyn and Kody didn't reveal much about their pregnancy, simply stating their excitement to be expecting a child together after trying for so long. However, Kody's third wife, Christine, may have hinted just whether the parents-to-be are expecting a little boy or girl.

"I'm so excited @LuvgvsUwngs is pregnant. I've been teasing her for months about having a baby girl for Truely to play with," Christine tweeted June 19.

Meri Hints At Trouble In Marriage?

If Christine's tweet revealed that Robyn is pregnant with a girl, it would be her 3rd daughter overall (she has two, Aurora and Breanna, from her first marriage), and her first daughter with Kody. The two already have a son, Solomon, together.

If the baby is a girl, it would be Kody's 11th daughter overall. Including Robyn's daughters, his others are Aspyn (with Christine), Mariah (with first wife Meri), Madison (with second wife Janelle)), Mykelti (with Christine), Gwendlyn (with Christine), Ysabel (with Christine), Savanah (with Janelle) and Truely (with Christine) .

It is unclear just how far along Robyn is in her pregnancy, or when she is due.
