Rae Dawn Chong, Oprah's Color Purple co-star disses her, drops the N-word.

Oprah Winfrey's former Color Purple co-star Rae Dawn Chong has launched a scathing attack on the talk show host.

Speaking on internet radio show Matty P's Radio Happy Hour, the Canadian actress, 52, drops the N-word and criticises the media mogul's weight and accuses her of being 'power-hungry'.

Rae, who has mixed Chinese, European and Afro-Canadian heritage, claims Oprah, 59, would have been a 'house n**ger' if she had lived before the emancipation of slaves.

Despite insisting she got on well with Oprah during the making of the Alice Walker film adaptation, her opinion changed when they made Commando, which was released the same year as The Color Purple.

Fans of the film will know Oprah played feisty Sofia in the film, while Rae played Squeak - the girlfriend of Sofia's husband Harpo (William E Pugh).

During the interview, which was first reported by TMZ, Rae swears frequently and uses the N-word twice when discussing Oprah.

Host Matty P is audibly shocked after Rae said: 'If you look at the way [Oprah] looks, she looks like 60 years ago she would have been a house keeper luckily. She would have not been a house n**ger she would have been a field n**ger

Rae has since attempted to issue an apology over the use of the racial slur in a video for TMZ.

However, she appears to stands by her attack on Oprah, despite claiming she meant to use the N-word as a 'compliment'. 

Rae originally said her opinion of Oprah soured when she was invited to Chicago to see her talk show.

She said: 'She was lovely (during The Color Purple). It was after when I starred in Commando with Maria Shriver's husband (Arnold Schwarzengger) is a movie, she was a total biatch (sic).

'She invited me to come to her show and she just wasn't having me. She’s competitive. She didn’t like me. She just wasn’t having me.

'They put me in a real s**tty hotel downtown and my son got sick and at the end of the day, it was just a nightmare.

'I ended up being backstage and she called me on stage and I was like, "You know what, f**k you b**ch." Oprah is all about Oprah.'

WoW, this woman has some serious deep issues with Oprah, hope she settles herself soon too. Hatred and anger burns YOU FIRST before it touches the other person.
