HarperCollins has acquired Priestley's memoir with their division Imprint HarperOne. It is slated to be published in Spring 2014.
"Although I've only been on the planet for 44 years, I've lived a lot in that time," Priestley said. "I hope my story will enlighten, entertain, and inspire those who read it."
Priestley, who received a multiple six-figure advance for the book, plans to talk about his time as heartthrob Brandon Walsh, the rift that developed between he and 90210 creator Aaron Spelling, his 2002 car crash and even his time in jail for driving drunk.
Priestley currently stars on the Canadian comedy Call Me Fitz.
