Teen idol Justin Bieber is asking his fans to stop sending Kim Kardashian death threats after the two posed together at the White House Correspondents dinner.

After Bieber jokingly called Kardashian his “girlfriend” on his Twitter page, the pop star’s two million Twitter fans began to threaten the sexy reality star.

I'm getting death threats from your fans!" Kardashian, 29, wrote to the singer Tuesday night. "This is unBeliebable!!!"

The teen star was forced to calm the hoards of angry Bieber Babies (like Beanie Babies, only meaner), telling them, “ladies calm down” and clarifying that Kardashian was only “a friend.”

"a very sexy friend but a friend," he Tweeted. "no need 4 threats. Let's all be friends and hang out often."

It wasn’t the first time the Bieber babies became aggressive – a group of about 500 trampled his own mother in New Zealand as they rushed to reach the young singer.

And just the day before, he was forced to cancel his show after they injured each other during Bieber mania!
