The “Fashion Police” presenter warned that the singer's ex-boyfriend will hit her again.

The 79-year-old star called Rihanna an “idiot” after watching her open up about Chris Brown to Oprah Winfrey.

“Rihanna confessed to Oprah Winfrey that she still loves Chris Brown. Idiot! Now it’s my turn to slap her,” Rivers tweeted.

Rihanna quickly responded: “Wow, you really do get slow when you’re old, huh?”
But it appears she has deleted the tweet.
Rihanna has recently opened her heart about ex-boyfriend who physically assaulted the 24-year-old singer.
In an interview to Oprah Winfrey she confessed to have feelings for Brown.
“We love each other and we probably always will, and that’s not anything that we’re going to try to change,” she said about Brown.
Joan used the micro-blogging website again to express some advice for the “Umbrella” hit-maker before inviting her to appear on her own show.

She warned: “Honey, Rihanna, everyone knows: If he hit you once, he’ll hit you again. Read the statistics. PS - Love to have you on ‘Fashion Police’!”
