Never, like, ever call Justin Bieber an idiot. We're not saying that simply because we're diehard Beliebers (though it's true), but because calling him names or insulting him simply can get really expensive, as company Wall Celebrity is finding out the hard way.

Bravado International Group Merchandising Services, which is the group behind The Biebs' merch and marketing, has filed a lawsuit in Manhattan Federal Court against Wall Celebrity, claiming that company breached its agreement by making disparaging comments about the 19-year-old singer.

Wall Celebrity came aboard to sell vinyl wall graphics of the Biebs, but when head honcho  Gianni Giannulli reportedly spoke out about the teen online and said he was an idiot, things got ugly. He was hit was a $100,000 suit, according to The New York Daily News.

While no one is perfect and people are certainly entitled to their opinions about Le Biebs, it's pretty boneheaded to insult or dis someone you are in business with -- especially when it's such a visible public figure like JB, who is known for lucrative revenue deals. That's pretty, well, idiotic.
