"Hurt like a b*tch," the reality star wrote in the caption accompanying the shiny new addition to her face.
She later posted another pic of her new piercing alongside a friend who has one, too, and wrote "twinsies."
Briana actually invited her fans to watch the whole thing, which she streamed live on UStream. Truth be told, we're actually kinda glad we missed that one because it makes us queasy just thinking about it!
What do you think of Briana's new piercing?
