The Biermanns Got Matching Family Tattoos for Ariana's 18th Birthday

Ariana Biermann will always remember her 18th birthday party, and not just because she got a visit from a stripper cop.

 The Don't Be Tardy family planned an epic blowout to celebrate Ariana's milestone birthday, complete with a tiered Hannah Montana-themed birthday cake, a cute ripped jeans birthday outfit.... and a visit to a tattoo shop for matching family tats.

A video on Hollywood Life's site breaks down all the details from Ariana's birthday. In the video, the party began with a visit from a fake cop who told Ariana she was in trouble for a hit-and-run in the school parking lot before stripping down to his boxers.

The whole crew then piled in a party bus to head to a tattoo shop. "We're about to get a f--king tattoo," Ariana says. She got not one tat but two, with a simple black cross on the side of her hand and then a red XOXO on her wrist.

Mom Kim Zolciak-Biermann, sister Brielle Biermann, and Don't Be Tardy Kroy Biermann patriarch joined in on that one, with the whole fam getting matching XOXO tattoos across their wrists. Apparently getting tattooed in this spot isn't painless.

"You see like a little tear come out of my eye," Ariana says in the video, while Kim says, "The wrist is crazy as hell, girl." (Kroy didn't think it hurt, though, which makes sense because he has a major shoulder tattoo.)
