'Beliebers' Threaten Model Lara Stone After CK Ads were Released

The latest Calvin Klein campaign featuring Justin Bieber and model Lara Stone might be too racy for some of the 20-year-old's fans. According to several reports, Bieber fans, known as Beliebers, have sent death threats to the 31-year-old Dutch model, telling her to stay away from the singer.

One user, @ameliebelieber6 wrote, "I'll kill that girl..." accompanied by gun and knife emoticons.

Another wrote, "Go kill yourself with a cactus."

One girl wrote "back off or i'll kill you, please and thanks. No pressure :).

@MaryBiebsxo, wrote, "Don't touch him again or I will kill you."

One more added, "hi bitch i hate u. touch justins d*** again and ill kill u im not joking."

Many of the images are quite provocative. In one of them, Stone straddles a bare-chested Bieber. In another one, Stone embraces the Canadian singer. In the short clip that accompanied the ads, Stone runs her hands over Bieber's naked chest and clothed crotch area.

Despite these violent responses, Stone's husband, comedian David Walliams, was able to joke about the ads. He tweeted: "Why has someone photoshopped @justinbieber's head onto what is clearly my body?" Shortly after, one of his fans sent him an altered photo of one of the ads with Walliams head on Bieber's body.

Stone has not made any comments on these death threats. Stone has worked with Calvin Klein before. These campaigns were Bieber's first with the brand.

"Calvin Klein is such an iconic brand and I am excited and honored to become a part of the Calvin Klein brand legacy with this campaign. I have been a longtime fan of the brand and have worn their jeans and underwear for a while, so this is kind of a dream come true," said Bieber. "This is the beginning of an exciting new year for me, personally and professionally, and being a part of this campaign has been a fantastic opportunity and experience."

The Calvin Klein Underwear and Calvin Klein Jeans campaigns were shot by Mert Alas and Marcus Piggott.
