@dailymail: Kim Kardashian has revealed the unusual rule she uses to protect her four children from news coverage about her and ex-husband Kanye West. The reality star says her household goes on 'lockdown' when she wants to shield them from current affairs, switching off TV and radio broadcasts in favor of movies and music. 'They don't have to be a party to this,' Kardashian said in Jonathan Van Meter's new book, Citizen Kim: The Woman Who Created the Future. She also admitted she still worries about West, saying: 'That's the father of my kids, I'll never not worry about him.' #kimkardashian #celebrity #realitytv #kanyewest
