The Mail quotes a source who claims: "The paramount rule - an unbreakable one - is an agreement that neither Kyle nor Annie will engage in any way with Lauryn Goodman or her children."
The source added: "This isn't just a matter of trust, but also, as we shall see, a response to Lauryn's behaviour, particularly online, which has been distressing for the couple and for their children. Neither Kyle nor Annie follow her on social media, and friends are asked not to repeat the stories she rehearses on her social media channels, or on television or in other interviews."
The Mirror also quotes a source claiming that any contact between Walker and his children is "done through the proper legal channels."
