Stephanie Pratt to pen tell-all book

LONDON, April 2 (UPI) -- Stephanie Pratt revealed plans to write a tell-all book about her life on-and-off camera during an interview for the May issue of British men's magazine FHM.

The 28-year-old reality star -- best known for her real-life role of being the younger sister of Spencer Pratt -- posed topless for the magazine's cover and dished on her forthcoming book in the accompanying cover story.

"It's coming out later in the year, and it's about me growing up," Pratt said, via the Daily Mail. "It's got stuff about family, getting everything I've ever wished for, my descent into drugs and rehab and arrests."

Pratt was arrested for a DUI in 2009 and for shoplifting in 2006. She entered a 30-day rehab facility after her second detention.

According to Pratt, the book will detail her time in the reality shows The Hills, Big Brother and Made in Chelsea as well as "stuff about" her controversial brother and the men in her life.

"I've been very honest," she said.
