Justin Bieber fans are bat shit crazy.

After images of his new Calvin Klein campaign with model Lara Stone surfaced, Beliebers across the world took to social media with their thoughts: Some were elated, some were jealous, and some were straight up pissed ... at Lara Stone.

The 31-year-old Dutch model has received a slew of threatening messages on Twitter following the release of the campaign, which features her grabbing Bieber’s bare chest and running her hands through his hair. The Telegraph is reporting that fans directed messages like “I’ll kill that girl…” and “Go kill yourself with a cactus” to Stone (most have been taken down since), who has yet to publicly respond to the backlash.

Check out some of the bitter tweets that have yet to be deleted below.

Here’s hoping these fans wise up and realize their little celebrity crush is no reason to act like a lunatic.
