Fans were left with their major burning question about whether or not Robyn was pregnant unanswered when Sister Wives ended its fifth season, but a new photo has sparked curiosity on whether or not a new baby has officially joined the family.

Brown Family Has A 'Peripheral' Realtionship With Their Religious Sect?

Meri, Kody's first wife, posted a photo of herself holding a brand new baby girl on her Twitter page September 19, introducing the world to her new niece-but fans wondered just who the baby belonged to.

"Loving being an aunt again to this little cutie, Saige : )," she captioned the shot of herself cradling the newborn.

However, the photo sparked wonder in her fans, who were curious whether or not the baby girl could have been one that Robyn gave birth to-making her a new child in the Brown family, but obviously not Meri's own child.

"@MeriBrown1 who's baby is that?" one fan asked on the photo.

"@merbrowder oh boy...this season is gonna be good," another fan commented.

Fans have been dying to know if Robyn was pregnant since before the fifth season ended in July, but questions about a pregnancy were all forbidden on the reunion show-which only served to spark curiosity even more.

Added to that, Kody tweeted twice during the show's final episodes of the season, hinting to fans that a baby was on the way.

"Super Sol! Thanks @LuvgvsUwngs A cute little boy! Only the 3rd child shy of 17...Should we have another? #SisterWives," he wrote on July 20.

He followed up one week later during the reunion show with "Nothing to say yet except: We are a great show for a First Response pregnancy test add! Uh...right?? #SisterWives," he wrote.

Fans will have to wait however until a new season airs to find out if a new Brown baby has been added to the family.
