Following the sexual harassment scandals that engulfed Hollywood in 2017, Meryl Streep, Shonda Rhimes, Ashley Judd, Emma Stone and Reese Witherspoon are among 300 Hollywood stars backing anti-sexual harassment initiative Time's Up!

You can read the full letter here and donate to the legal defense fund here.
A legal defence fund, backed by $13 million in donations, which will focus on less-privileged working class women fighting sexual misconduct in their workplaces and the fallout which results from reporting it.
It has already overseen the creation of a commission, announced in December, that is tasked with creating a blueprint for ending sexual harassment in show business.
And a request that women walking the red carpet at the Golden Globes speak out and raise awareness by wearing black.
The fund will be housed at and administered by the National Women's Law Center, a women's rights legal organization, and managed by Christina M. Tchen, former Chief of Staff to Michelle Obama.
Producer Shonda Rhimes is also a prominent member, alongside showrunner Jill Soloway; Donna Langley, the chairwoman of Universal Pictures; lawyer Nina L. Shaw; and Maria Eitel, an expert in corporate responsibility who is co-chairwoman of the Nike Foundation.
It also calls for "gender inequality and the imbalance of power" to be addressed, stressing the need for more women to gain positions of authority and parity of pay.
