Lindsay Lohan praises her and Justin Bieber's moms for speaking out against abuse

Lindsay Lohan has praised her mother and Justin Bieber's mom for going public with their experiences with abuse and urged her fans to reach out for help if they find themselves in similar situations.

Dina Lohan has been vocal about the domestic abuse she allegedly suffered while married to the Mean Girls star's estranged father Michael, and most recently accused her ex of locking her in a closet during their turbulent relationship.

She told U.S. news show Entertainment Tonight, "I was physically abused, locked in closets... I have police reports, I have hospital records, I have pictures of the black eyes."

Her claims have been blasted by Michael Lohan, but that hasn't stopped Lindsay from voicing her support for her mother on her Twitter.com blog.

The actress has also expressed her admiration for Bieber's mom Pattie Mallette, who has opened up about the sexual abuse she endured as a child in her new memoir, Nowhere But Up: The Story of Justin Bieber's Mom.

In a series of tweets on Friday (28Sep12), Lindsay writes, "I think @justinbieber's mom Pattie Mallette & my mom @dinalohan are so strong for speaking out about their stories. It's women like this... who make a difference in the world.. They encourage us to be strong. Thank you to @dinalohan & pattie mallette for being such strong women.

"Don't be afraid to speak to someone about verbal, sexual, or any kind of physical abuse. It's your life & you are in control of your destiny".

Lohan also gives Mallette's book a little free promotion, adding, "go out and buy Nowhere But Up".
