Justin Bieber, Pay $3 million or don't tall anyone you where here -- at my party!

Justin Bieber threw a party on Friday (Nov. 15) and he made all his guests sign a confidentiality agreement. In a formal contract obtained by TMZ, everyone in attendance "agreed not to tweet, text, phone, Facebook, record, write or in any other manner spill the beans on what went on inside" at risk of paying the petit Canadian $3 million -- "no trial, no arguing, just pay up."

So this days you can actually go to a big celebrity party,
But..... Don't tell anyone you where there!?
