It’s his party and he can sue you if he wants to. Pop singing sensation Justin Bieber is threatening party guests with a $5 million lawsuit, according to a nondisclosure agreement released on Wednesday.

TMZ obtained a copy of the document that says attendees at any of Bieber's house parties in Calabasas, Calif., are subject to sign a waiver agreeing not to discuss what happens in the mansion. The liability waiver and release form states that those in attendance are subject to a fine if they discuss any of the events and are subject to paying $5 million in damages.

According to the document, those in attendance are demanded to refrain from tweeting, blogging or sharing Instagram photos from any said parties. Guest are also told to not comment on the singer’s “physical health, philosophical, spiritual other views and characteristics.”

The controversial NDA warns guests that activities taking place inside Bieber’s parties are “potentially hazardous,” telling invitees that by signing the form, they’re agreeing that the musician isn’t liable for inherent risks such as death, catastrophic and minor injuries from voluntary participation. Another warning states that guests shouldn't participate in such unidentified activities “unless they are medically able and properly trained.”

Bieber previously tried to block onlookers from entering his California neighborhood in April after a reality TV producer was eyeing the area for the program “Calabasas 91302,” in which TV cameras hoped to get a cameo of the 19-year-old pop singer. Residents reportedly released an outpouring of concerns regarding the program after the show aimed to get “an inside look at the true Calabasas life and all that entails.”

The singer was last seen at the Billboard Music Awards on Sunday after he was booed while making his acceptance speech for winning fan-voted the “Milestone Award.” Bieber has yet to comment on the NDA report.
