The actress said she got along well with Winfrey when the two starred in "The Color Purple," a film about black life in the 1930s. But she said Winfrey became "a total biotch" afterward, when Chong got a part in the Arnold Schwarzenegger action picture "Commando."
In an appearance on "Matty P's Radio Happy Hour," an Internet radio show, Chong said Winfrey "just wasn't having me."
"She's competitive. She didn't like me," Chong said.
She then went on a rant about the talk show host's appearance, TMZ reported Saturday.
"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,]" Chong said.
Chong later released a video saying she meant her use of the N-word to be a compliment to Winfrey, though doesn't explain how.
She said she regrets using the word.
