"Sweethearts" is the true story of one of Hollywood's greatest cover-ups: the love affair between Jeanette MacDonald and Nelson Eddy. Known as 'America's Singing Sweethearts' of the 1930s and 40s, they made eight box office hits together for Metro-Goldwyn-Mayer and became the most popular singing team in movie history. Rumor had it that they hated each other off-screen but the truth was that they were in love. Interference by MGM studio boss Louis B. Mayer triggered a series of tragic events that caused them to self-destruct their film careers, health and ultimately their lives. Discussed candidly in the book are Jeanette's four pregnancies by Nelson, her affair with studio boss Louis B. Mayer and her marriage to bisexual Gene Raymond. Nelson married a mentally unstable woman, Ann Franklin, who blackmailed him into marriage, threatened to disfigure Jeanette, and vowed to go to the press with the scandal if Nelson tried to divorce her. Nelson turned to young women when he and Jeanette were at odds, and several of them have gone on record in this book for the first time. Despite all, Nelson and Jeanette had a fierce, spiritual bond and loved each other to the end. The author was a close friend of Jeanette's older sister, actress Blossom Rock, interviewed over 200 people, including celebrities, plus had access to a wealth of unpublished letters and memoirs.
