Justin Bieber reportedly asks guests who visit his home to sign a secrecy agreement - which could land them a five million dollar fine if they break it.
The teenage pop star splashed out on a swanky mansion in the Los Angeles suburb of Calabasas last year and TMZ.com has apparently published a Liability Waiver and Release form which asks guests not to reveal anything that goes on inside the 19-year-old's pad.
The agreement reportedly states that visitors must not reveal anything about "physical health, or the philosophical, spiritual or other views or characteristics" of Justin or other guests.
It states that anyone who breaks the terms could be liable to pay five million dollars to the singer in damages, TMZ reports.
The reported waiver, common practise among Hollywood stars, comes two months after photos emerged of a party at Justin's house - which includes a library, a private cinema, a bar, a wine cellar and a pond - while he was away on tour in Europe.
