Oprah Winfrey is a giant pile of bad, says her "The Color Purple" co-star Rae Dawn Chong.

Right -- Rae Dawn Chong, star of "Soul Man" and semi-recently a guest actress on "That's So Raven," is ripping Oprah.

She called Winfrey a self-centered fat "biotch" who would have been a "house (N-word) back in the slave days."

Yikes. I wouldn't get too close to Rae Dawn Chong anytime soon, as there's got to be a contract out on her by now.

According to TMZ, Chong recently appeared on "Matty P's Radio Happy Hour" and talked about how her relationship with Winfrey from good to bad in the 1980s.

Chong said Winfrey was "lovely" to her back on the set of "The Color Purple" in 1985, but when Chong moved on to her next movie, "Commando," she said Winfrey became "a total biotch."

"I starred in 'Commando.' And she just wasn't having me. She's competitive. She didn't like me. She just wasn't having me."

Yes, of course Oprah Winfrey would be jealous of Rae Dawn Chong doing "Commando." Either that, or someone been getting into her dad's -- famous stoner comedian Tommy Chong -- stash.

Chong even went so far as to attack Winfrey's looks and invoking slave imagery.

"If you look at the way (Winfrey) looks, she looks like 60 years ago she would have been a house keeper luckily. She would have not been a house (N-word) she would have been a field (N-word)."

"Shes so enormously insecure," Chong added. "If you want to distill Oprah Winfrey down to like her most basic components. She wants to be beautiful."

Yes, it's obviously Oprah Winfrey who's insecure.

"Imagine being (Oprah)," Chong said. "She has all of the world. All the power in the world ... and she only wants something that is only chemical, purely impossible."

A cell phone that runs on human saliva?

"The thing that's really great about Oprah that you can't take away from her is that she's a great brown-nose."

Sounds like Oprah wouldn't give someone an intern job.

Rae concluded the interview with something that almost sounded like a compliment ... but not really. "No matter how vile she is, you kind of gotta go, 'hello hats off' like, you've done an amazing thing you have actually shifted the DNA of the universe."

Right. Thanks Rae Dawn.
