Ellen Pompeo has hit out against so-called reverse racism.

The 'Grey's Anatomy' star has recalled the moment she called out the A&E Network over a documentary about the Ku Klux Klan, and she was heavily criticised for celebrating the programme being pulled by tweeting a black fist emoji.

Speaking on Facebook Watch show 'Red Table Talk', she said: ''I'm not appropriating culture. I'm just joining the fight.

''If you call me a white b***h then isn't that judging me on the colour of my skin? Why can't I help a victory for black people because I'm white?''

Ellen, 49, was met with a fierce backlash over her tweet and subsequent response to criticism, as she told one critic to not be ''a hater''.

She tweeted: ''Don't be a hater I do it because racism is not just a black problem it is all of our problem get it??? (sic)''

She later added: ''I'm so sad that people attacked me over standing up for equality I'm sad that people chose anger and I'm sorry if I offended anyone. (sic)''

The row occurred shortly after Ellen discussed diversity in Hollywood for Porter Magazine's Women in Television issue alongside Gabrielle Union, Gina Rodriguez and Emma Roberts.

She argued: ''This day has been incredible. And there's a ton of women in the room. But I don't see enough colour. And I didn't see enough colour when I walked in the room today [and saw the staff].

''As Caucasian people, it's our job, it's our task, it's our responsibility to speak up in every single room we walk into. It's our job because we created the problem.

''When I show up on set, I would like to see the crew look like the world that I walk around in every day, and I think it's up to all productions to make sure that your crew looks like the world we see. It's the first thing I notice when I walk in a room.''
