London: Teen pop star Justin Bieber`s fans have sent reality TV star Kim Kardashian death threats after the singer called her his girlfriend on Twitter.
The `One Time` hitmaker met the 29-year-old star at the White House Correspondents` dinner in Washington over the weekend and Bieber later posted a picture of the pair on the micro-blogging site and called Kardashian his `girlfriend.`
However, fans of the 16-year-old singer were not happy with this and have lashed out at the `Keeping Up With The Kardashian`s` star, reported MTV online.
The reality TV star reached out to Bieber on Twitter, writing, "Seriously Biebs! I`m getting death threats from your fans! This is unBeliebable!!!"
Bieber responded to Kardashian on Twitter, telling his fans, "Ladies calm down. Kim Kardashian is a friend. A very sexy friend but a friend. No need for threats. Let`s all be
friends and hang out often." Bieber has previously stated that he likes older women, especially Kardashian.
"I think she`s cute. And, no, she`s not too old for me," he had said.
