Lily Collins opens up about tough relationships for memoir

Actress Lily Collins has revisited "dark places" from her past to share her lessons about love and life in her first memoir.

The Mirror Mirror star has put pen to paper to give fans an insight into her life behind the camera, revealing growing up as the daughter of rock icon Phil Collins wasn't a smooth ride.

Unfiltered: No Shame, No Regrets, Just Me features a collection of inspirational essays, through which Lily will explain how she learned to accept her flaws and find her inner strength and confidence.

"It's definitely like having my diary published," the 27-year-old tells People.com of digging up personal details for readers.

Lily credits working with Hollywood veteran Warren Beatty on the actor/filmmaker's new romantic drama Rules Don't Apply with teaching her to "just let go" of her emotions, and it helped the star process the tough experiences from her past for the memoir.

She explains, "I was put into many situations throughout the years in acting, in Warren's film especially, where you're in an intense situation and you have to fight your way through it, go through the emotions, and live and breathe those scenes."

Collins admits some of her darkest moments have been in romantic relationships, and while she refuses to identify the exes who caused her pain, she wants fans to understand the lessons she took away from the trying times.

"It was not about attacking, it was about showing how you can be given situations in life and turn them into lessons," she shares. "This is my way to open up conversation with young women and say, 'Hey, we're all the same.'"

Lily, who is known for keeping her love life private, has previously been linked to fellow actors Jamie Campbell Bower, Zac Efron, Taylor Lautner, and Thomas Cocquerel, while she was also spotted out on a series of dates with pop star Nick Jonas earlier this year (16).

Unfiltered: No Shame, No Regrets, Just Me will be published through HarperCollins in March, 2017.
