LOS ANGELES (PA): Justin Bieber reportedly asks guests who visit his home to sign a secrecy agreement - which could land them a $5m fine if they break it. The teenage pop star splashed out on a swanky mansion in the 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 states that visitors must not reveal anything about “physical health, or the philosophical, spiritual or other views or characteristics” of Justin or other guests.
