Justin Bieber fans threaten Lara Stone over new Calvin Klein campaign

Justin Bieber fans have responded to the new Calvin Klein campaign with threats of violence.

Justin Bieber fans have taken offence to the new Calvin Klein ad campaign and threatened to kill model Lara Stone, who he stars alongside.

The racy advert released yesterday for the underwear and jeans divisions of Calvin Klein starring the popstar alongside model Stone have been subject to abuse online by members of Bieber's fanbase.

In the video, which has already been watched 482,000 times on Youtube since it was released yesterday, Stone is pictured enjoying an intimate embrace with the pop-singer.

This is the first major fashion ad campaign for Bieber, 20, who shot to fame in 2009 and quickly garnered a global fanbase nicknamed 'Beliebers'

The overzealous activities of his fans have been well documented; from damaging his museum waxwork from excessive groping to converting to Islam to win tickets to his concert.

The ad has already been parodied by none other than Stone's comedian husband, David Walliams, who shared the campaign with Bieber's head edited out and replaced with his own.
