The 44-year-old "Charmed" star made the comment following reports Thursday that numerous actresses who would be attending the 75th Annual award show in January were planning on wearing black as a sign of solidarity in protest of things like gender inequalities in Hollywood and sexual harassment in the entertainment industry.
In addition to Streep, who has spoken out vocally against Weinstein despite working with him on August: Osage County and The Iron Lady, Jessica Chastain and Emma Stone are those who are said to be wearing black. "I despise your hypocrisy", she wrote on Twitter.

But, McGowan - who was one of the first women to come forward with rape allegations against Weinstein - is not impressed.
In a statement to ABC News, Weinstein denied any allegations of non-consensual sex.
