French first lady Valerie Trierweiler Paris - Arabstoday French first lady Valerie Trierweiler plans to sue the authors of the latest book about her because it spreads malicious rumours, her lawyer said Wednesday. Trierweiler, a 47-year-old journalist and partner of President Francois Hollande, is suing the authors of \"La Frondeuse\" (The Rebel) -- a biography due to be published on Thursday, for breach of privacy, lawyer Frederique Giffard told AFP. The book is the latest in a string of works on Trierweiler that have appeared since the Socialist Hollande was elected in May. They focus on her alleged feud with the president\'s ex-partner Segolene Royal, who is the mother of his four children.
