We Were Not Expecting Ariana Biermann's Nickname for Brielle Biermann

We're getting to know the Biermanns in a whole new way during Season 8 of Don't Be Tardy as they take us along for the ride of their epic family road trip. In fact, we just learned something about Brielle and Ariana Biermann's relationship that has us fully shocked.

During the "Road Trip Quiz" edition of Season 8, Episode 2, which aired on October 13, it was revealed that Ariana's nickname for Brielle is Bobcat. Now, we don't exactly know what inspired this moniker, but we do know that Ariana does often call her big sis by this name. Ariana captioned one photo of the siblings posted on Instagram on May 31, 2019, "My bestie bobcat."

Ariana also wrote, "I love you bobcat," along with a white heart emoji in the comments to a post of her and Brielle showing off their brunette looks that was posted on Brielle's Instagram on June 10.

During this special episode of Don't Be Tardy, we also got more insight into what Brielle and Ariana were like in their younger years with mom Kim Zolciak-Biermann describing her daughters as "fun" and "fearless" kids, respectively. Brielle also describes her family as "chaotic" (in a good way, we're sure!), while Ariana adds that they're "full of life," too. And when it comes to keeping the peace in the Biermann bunch, "Brielle and Ariana are the best peacemakers in the family, according to Kim."
