– If you aspire to attend a party at Justin Bieber's house, first you'll have to score an invitation ... and then you'll have to sign a Liability Waiver and Release. TMZ got a copy of the fairly insane document, which says that if you tweet, blog, text message, or otherwise talk about the party in any way, shape, or form, you owe the Biebs $5 million. Not only can you not discuss the party; you're also not allowed to discuss the other guests' health or philosophical and/or spiritual views. Yep, it specifically says that. By signing the form, you also acknowledge that some of the party activities are "potentially hazardous and you should not participate unless you are medically able and properly trained," because you risk "minor injuries to catastrophic injuries, including death." (Oh, and you agree not to sue Bieber, should you be catastrophically injured during a crazy game of beer pong.) TMZ notes that other stars make partygoers sign similar waivers, but notes that Bieber's is nonetheless "hilarious." (Click to find out which fellow singer thinks Bieber is an "a--hole.")
