The 46-year-old actress - who is now married to Brad Falchuk - went through a divorce from Coldplay frontman Chris Martin in 2016 after 12 years of marriage. Now she wants to pen a tome about her experiences with remaining close to Chris, because she thinks their bond is special.
Gwyneth - who is still friends with Chris for the sake of their two children, 14-year-old Apple and 12-year-old Moses - said: "Both Chris and I have made a commitment to continue to love the things about each other that we've always loved and to really continue to develop our friendship and to find ways to continue to communicate.
"There's been a long process to it. At some point maybe I'll write a book, because you really have to focus on forgiveness and spite that comes up; you have to let it go."
The Iron Man actress says things weren't always easy post-divorce, but the pair pushed through the awkward years in order to "maintain the family structure".
