Kim Kardashian and Kanye West's wedding guests will be forced to hand in their phones prior to the ceremony and will have to sign a confidentiality agreement.
The couple are set to tie the knot in Paris in May, but they want everyone who attends the nuptials to promise not to share any details with the media and to hand over their phones prior to the ceremony.
A source told RadarOnline: "Guests will have to go through extensive security, even most of Kim and Kanye's celebrity friends.
"Mobile devices will be held at a secure location and if someone needs to use their's during the festivities, accommodations will be made, but a long way away from the festivities. This is all designed to discourage guests from using their phones."
If anyone breaks the terms and conditions of the contract, it is believed they will be sued.
However, Beyoncé and Jay Z are among the few that will not be forced to sign a contract, nor will they have to give up their mobile phones, as Kayne is confident they will not betray his trust.
The source explained: "There is no way Kanye would ever even dare to ask Jay Z or Beyoncé to sign a non-disclosure agreement, or take away their cell phones.
"He knows that neither one of them would betray his trust."
Kim, 33, and Kanye, 36 - who have nine-month-old daughter North - are reportedly licensing their wedding photos for sale and have agreed to broadcast their big day on their E! reality TV show 'Keeping Up With The Kardashians'.
