Oprah Winfrey has made a second plea to Rihanna, telling her to stay away from Chris Brown.

In a special report on domestic violence, yesterday, the chat show host insisted that the Run It star will assault his girlfriend again.

"Both Chris Brown and Rihanna, if I were your friend, I would call you up and I would say, 'Give it some time, get yourself some counselling, take care of yourself, heal yourself first," Oprah said.

"Love doesn't hurt. I've been saying this to women for years - love doesn't hurt.

"And if a man hits you once, he will hit you again. He will hit you again. I don't care what his plea is, he will hit you again."

Oprah dedicated her show to the controversy surrounding Chris and Rihanna's alleged altercation, which took place on February 7.
