Kim Kardashian Isn't Dating Justin Bieber, So Stop Sending Her Death Threats

Bieber Fever reaches, um, fever pitch when his fans attack Kardashian on Twitter after he calls her his "girlfriend"

This is what happens when you mess with the Bieberverse.

Kim Kardashian learned the hard way that there's one group of rabid, boy-child-loving fans that it's best to steer clear of, and they're the ones who have no life love Justin Bieber.

And to think, it all began with an otherwise harmless tweet…

"Look its my girlfriend," the 16-year-old pop phenom tweeted last Saturday, posting a photo of himself and Kim at the White House Correspondents' Dinner.

No problem, right? Well, no problem until Kim had the gall to respond with the following hate-inducing revelation:

"I officially have Bieber Fever!!!"

The nerve! That, apparently, was enough for Bieber lovers the world over to rise up en masse and attempt to take down the woman that stood between them and their most likely illegal love for the Biebster. (Katy Perry seemingly posed no such threat.)

"Seriously Biebs!" Kardashian fired off yesterday. "I'm getting death threats from your fans! This is unBeliebable!"

It's unclear if Kim was attempting an improperly-executed Bieber pun or if the threats from the teen dream's legion of ladies simply got to her on that last tweet.

Enter Bieber, the lone voice of reason.

"Ladies calm down," he tweeted this morning. "@kimkardashian is a friend. a very sexy friend but a friend. no need 4 threats. Let's all be friends and hang out often ;)"

Either way, let this be known: You mess with Kim, you mess with the entire E! family. Consider yourselves warned.
