After being photographed together at the White House Correspondent's dinner and subsequently flirting on twitter, Kim Kardashian is receiving death threats from enraged Justin Biber fans. See, this is why 45-year-old ladies shouldn't be allowed to go on the internet.

After she mingled with the teen idol Saturday at the White House Correspondents' dinner in Washington, D.C., she Twittered that she had "Bieber fever."

He quickly replied, calling her his "girlfriend." Now, the E! reality star, 29, has Twittered, "I'm getting death threats from your fans! This is unBeliebable!!!" Bieber, 16, is shocked. "Seriously?" he responded. (Source)

Well what do you know. It turns out "Bieber Fever" can be lethal after all. I wonder if it's worse than the Swine Flu? Either way, if I were a certain 12-year-old lesbian, I'd be mighty scared of being locked in a bubble in a cage in the secret headquarters for Disease Control and Prevention. With no hair product.
