LAURIE HERNANDEZ, 16
What comes first — your memoir or your driver's license? For Hernandez, the former doesn't come long after the latter! The 16-year-old gymnast is publishing her first book, I Got This: To Gold and Beyond, in early 2017, and after the past few months she's had — winning gold and silver medals at the Olympics and competing on Dancing with the Stars — we're sure she has lots to say.

LILY COLLINS, 27
In a soon-to-be-released memoir, titled No Shame, No Regrets, Just Me, Collins says she's getting really personal. "It's definitely like having my diary published," she shares. In the book, the daughter of singer Phil Collins will discuss past relationships and intense roles she's taken on-screen, among other topics.

SIMONE BILES, 19
Biles will release her first memoir before she hits her 20th birthday, but if anyone has lived a publication-worthy life in 19 years, it's her. Born to a drug-addicted mother, she was placed in foster care at an early age before being adopted by her maternal grandparents. She began gymnastics classes at age 6, leading to a career that's earned her 14 World Championship medals and four Olympic golds.

GABBY DOUGLAS, 16
Though she's yet to turn 21, Douglas has authored two books since taking home the all-around gold in London back in 2012. The first, Raising the Bar, is a big-picture look at Douglas's life, filled with facts and images of her at the gym and off gymnastics duty. The next, Grace, Gold, and Glory My Leap of Faith, is an autobiography.

MILEY CYRUS, 17
Cyrus published her first memoir at age 17, but acknowledges that her story is far from finished in the title: Miles to Go. In it, she talks going from relative obscurity to mega-fame with Hannah Montana, and staying true to her roots after the fact. We'd bet that the past seven years hold enough material for another book.

DREW BARRYMORE, 16
If anyone has the life experience to write a memoir at an extra-early age, it's Barrymore. She nabbed her first on-screen credit at age 5, and shot to fame at age 7 in E.T. the Extra-Terrestrial. This notoriety came with some drawbacks, too: early exposure to drugs and alcohol, which led to addiction in her teenage years. In Little Girl Lost, she talks battling her demons and getting her life back on track.

JUSTIN BIEBER, 18
Like Cyrus, Bieber acknowledges that he still had lots of life ahead of him in the titles of his books (yes, plural), Justin Bieber: Just Getting Started and Justin Bieber: First Step 2 Forever: My Story. Though the publishing company calls the books "memoirs," Bieber took to Twitter to clear things up. "It isn't a memoir," he wrote. "We can all agree I'm a little too young to write a memoir. I just got a lot more life to live."

SHAWN JOHNSON, 20
Johnson took home four medals at the 2008 Olympics in Beijing, but didn't release her memoir until 2012, after she retired from elite gymnastics. The book, titled Winning Balance: What I've Learned So Far About Love, Faith, and Living Your Dreams, talks about her career as a professional athlete as well as her life after the Olympics. She's released two other books, too: in 2008, a collection of photos and quotes, and in 2016, a novel about a young gymnast.

JAMIE-LYNN SIGLER, 21
In her memoir, Wise Girl: What I've Learned About Life, Love and Loss, the actress talks about reaching fast success (and fame) with The Sopranos, her battle with Lyme disease and overcoming an eating disorder in her later teenage years.

KELLY OSBOURNE, 24
She had her private life broadcast on MTV from the time she was 17 years old, so it only made sense for Osbourne to publish her side of the story within a few years of the series' finale. In Fierce, she gives an inside look at the Osbourne family off-camera.

BRITNEY SPEARS, 18
By the time Spears hit adulthood, she had seen more success than most people see in a lifetime. You know what that means: time to write a book! She and her mom Lynne penned Heart to Heart, chronicling her life to that point and providing advice for conquering road blocks in life.

What's life really like for a young heiress? Hilton tells all in her 13-year-old autobiography, Confessions of an Heiress, in which she shares a few secrets and dishes on that famous scandal — plus gives readers tips on how to replicate her lifestyle with advice and product recommendations.
