Preity Zinta has set her eyes on writing an autobiography and knowing how feisty and straightforward she is, it will be an explosive one. BT has learned that this decision comes after many publishers, including a top international publishing house, approached the sassy actress asking her for permission to appoint a writer to chronicle her biography. They apparently wanted Preity to reveal everything about her tryst with the underworld when she got extortion calls from the mafia, to her relationship with Ness Wadia and even to her recent IPL crisis.pr
