Lily Collins faces the "same insecurities" as all other women her age.
The 27-year-old actress has admitted that despite her burgeoning career and enviable wealth, she still struggles with fears and self-doubt.
She shared: "I experience the same things that they [girls] do and face the same insecurities."
But Lily, who is the daughter of music icon Phil Collins, said that social media has enabled her to discuss her deepest insecurities with other women from all over the world.
She told the Autumn 2017 issue of Gritty Pretty Magazine: "Social media has allowed me to communicate with girls all over the world.
"It's always been really important to me that they know I experience the same things that they do and face the same insecurities.
"It's such a powerful tool to get to use in order to have conversations and reassure them that they're never alone in their struggles."
Lily's confession comes shortly after the actress said she had forgiven her father Phil for "not being the dad I expected".
Lily, who has battled anorexia and bulimia, revealed she had forgiven him for being absent at crucial moments in her life.
In her debut book, 'Unfiltered: No Shame, No Regrets, Just Me', she explains: "I forgive you for not always being there when I needed and for not being the dad I expected.
"I forgive the mistakes you made. And although it may seem like it's too late, it's not. There's still so much time to move forward."
Lily also revealed she has learned how to "accept" her father's perceived failings.
She wrote: "We all make choices and, although I don't excuse some of yours, at the end of the day we can't rewrite the past.
"I'm learning how to accept your actions and vocalise how they made me feel. I accept and honour the sadness and anger I felt toward the things you did or didn't do, did or didn't give me."
