The newest member of the Brown family officially has a name!

Baby Number 18 Has Arrived For The Brown Family!

Sister Wives stars Robyn and Kody have announced that their little girl, who was born on January 10, has officially been named Ariella Mae, and the family wasted little time sharing family photos on social media where they finally acknowledged her name.

Janelle, Kody's second wife shared a photo over the weekend of her son, Hunter as he held his new half-sister.

"Hunter and baby Ariella," she captioned the shot.

However, while the family is obviously in love with little Ariella, fans may be having a mixed reaction about the baby news, despite it breaking over the summer that Robyn was pregnant. Some have shared support over the news on social media, with one fan even asking Robyn how to actually pronounce their daughter's name, because she wanted to make sure she was saying it correctly, which Robyn responded to.

"Is it air-iella or 'aaahh-riella'? Hope it makes sense. Want to say your sweet girl's name properly. #ariellamae," the fan asked.

"'Ar' like in star. It is Hebrew. We will call her Ari or Aria for short," Robyn wrote.

However, other fans have still expressed displeasure with the family on posts of the news, with some comments expressing hatred for Kody and Robyn on the show's Facebook page, as well as some criticisms over the name they chose.

"I love watching Sister Wives, but please, no more babies. Kody told Meri 'No' to trying for another baby. It's not right or fair that Robin got pregnant after that and Kody allowed it to happen. Enough!" one fan wrote.

"Pretty close to her other daughters name," another added.

"Why does Robyn name her girls after Disney princesses..." another said.

"That name is too close to areola!" a fourth wrote.
