News that Justin Bieber was hit with a paternity suit by 20-year-old Mariah Yeater has shaken the Biebersphere to its very core. Could you believe that some Beliebers are not happy with the young woman who claims to have deflowered 17-year-old Bieber?

Yeater better hire a security detail. Her lawsuit has activated the legendary Belieber hivemind to an almost biblical extent. No Belieber worth her hashtag believes Yeater for a second. Judging from Twitter, Narnia has become tween shorthand for something as utterly impossible as Bieber fathering Yeater's baby. As in: "Mariah Yeater is pregnant with Justin Bieber's baby? Yeah, and I live in Narnia." A lot of 15-year-old girls are living in Narnia today.

There are plenty of death threats, too, since Beliebers are the fan equivalent of Los Zetas.

"Roses are red, violets are blue mariah yeater we are gunna kill you," tweets a user whose bio says she is "living my dreams.♥"

Maybe someone better-versed in North American Tween can explain what this comment, posted to one of the dozens of anti-Yeater Facebook pages that have sprung up, means: "UHHHH SHES A DISSCREASE!"

Justin Bieber, meanwhile, blithely tweets that he is "going to ignore the rumors…and focus on what is real. an opportunity to help by doing what i love. judge me on my music!"
