The "Magic Mike" star also explained that her "donation will be divided equally between the ACLU, with a particular focus to stop violence against women, and the Children's Hospital of Los Angeles, where I have worked as a volunteer for the past 10 years alongside organizations like the Art of Elysium."
She added, "Over the years, I have seen firsthand how more funding for staffing, better equipment and better medication can make the difference between life or death for a child. I know these organizations will put the funds to good use and look forward to continuing to support them in the future. Hopefully, this experience results in a positive change in the lives of people who need it the most."
Anthony Romero, executive director of the American Civil Liberties Union, told E! News that the organization is "incredibly grateful that Ms. Heard has so very generously shown her support for the important and necessary advocacy for victims of domestic violence."
