Amber Heard is reportedly keen to start "sharing her truth" with an explosive tell-all memoir, in which she would lay bare the details of her turbulent two-year marriage to Johnny Depp and their bitter court battle after he successfully sued her for defamation over an op-ed she wrote about being a victim of domestic abuse, reports aceshowbiz.com.

The 37-year-old actress- who is currently living in Madrid, Spain, with her two-year-old daughter Oonagh - would be looking for around $15 million for her story but is ready to speak out after being harassed online during last year`s trial, according to sources from RadarOnline.com.
