Melissa Leo, 50, who won an Oscar this year for her work as Mark Wahlberg and Christian Bale‘s mother in The Fighter, is writing a memoir that promises to be revealing. Publisher Simon & Schuster says the book will cover Leo’s decades of working in both television and film, as well as her childhood and her stormy relationship with ex-boyfriend actor John Heard, who is also the father of her 24-year-old son, Jack. In 1997 Heard was charged with stalking Leo, Jack and her new boyfriend, and with harrassing her by phone. The autobiography is slated for release in 2013. ~Alexandra Heilbron
