Don't ever mess with the "Beliebers", they can send threats just like what Calvin Klein model Lara Stone is experiencing right now.

Stone has posed with Justin Bieber in a daring photoshoot for Calvin Klein. Stone was topless and casually caressing Bieber as a pose for the print ad.

 It has sparked a negative reaction among the singer's fans.

One tweet from a fan wrote, "I'll kill that girl. . ." which also featured emojis that had three guns and one knife pointing at two faces.

Another Twitter user had used profanities as a form of retaliation, ending the tweet with, "I'll kill you and I'm not joking."

One Twitter user also said, "Back off or I'll kill you. Please and thanks, no pressure" Ending the tweet with a smiley, made it seem less hostile.

But Stone has never responded to any of these negative tweets.

Instead, she retweets the other Twitter users who have praised the shoot.  

There seems to be no threat here since the 31 year old model is happily married to British comic David Walliams. The couple has one child together.

Stone has graced Chanel, MaxMara and Balmain runways.

A  six second promotion teaser was released in Calvin Klein's official Twitter account. Bieber has shown off his rapid drumming skills thus it was captioned as "Drum roll.. #mycalvins"

The teaser ended with Bieber pulling in Lara Stone for a kiss, which was deemed as a daring move for the pop star.

MailOnline was the first to confirm in July that Bieber had starred in a Calvin Klein ad and had hoped that the results will be released earlier in that year.
