Here's the good news ... Justin Bieber
wants to invite you to one of his house parties. The bad news ... if you talk about it, he's gonna sue your ass for $5 million.
TMZ has obtained a copy of a document EVERYONE must sign before entering Casa De Bieb in Calabasas, CA. The doc -- a Liability Waiver and Release -- warns that anyone who blabs about any of the goings on inside the mansion will get nailed, and that includes the "physical health, or the philosophical, spiritual or other views or characteristics" of Bieber or the guests.
