Alaska’s favorite spawn BRISTOL "The Pistol" PALIN will be going toe-to-toe with mommy SARAH on Best Seller lists as tell-all memoir announced by publisher.

Bristol, 20,  has inked a deal  has signed with William Morrow to publish Not Afraid of Life, to hit booksellers summer.

Morrow, an imprint of HarperCollins, announced Tuesday that the memoir would provide "an inside look at her life."

"Bristol gives readers an intimate behind-the-scenes look at her life for the first time, from growing up in Alaska to coming of age amid the media and political frenzy surrounding her mother’s political rise; from becoming a single mother while still a teenager to coping as her relationship with her baby’s father crumbled publicly — not once, but twice," Morrow’s presser says.

A listing for the Bristol book briefly appeared last month on and on an online HarperCollins spreadsheet.

"She speaks candidly of her aspirations for the future and the deep religious faith that gives her strength and inspiration," the blurb ballyhoo-ed.

Expect ex baby dada Levi Johnston to receive a lit lambaste.

The pub didn’t divulge how much payola The Pistol pocketed for the deal.

Morrow are the same folks who pubbed mommy Sarah’s memoirs.
