Oprah Winfrey’s interview with Rihanna airs next Sunday night, but here's a preview . . . Rihanna broke down and cried while discussing her assault at the hands of Chris Brown.  She said, "It was embarrassing.  It was humiliating.  I lost my best friend." She added, quote, "I was resentful.  I held a grudge.  I was dark."  (There's no word if she goes into detail about what their relationship is like now.  Check out a preview clip here.)

So what was Oprah's take-away from the Interview?  She expected Rihanna to be HARDER. Oprah says, "I thought she would have been kind of a bad-ass kind of a rocker hard-edge woman . . . nothing could have been farther from the truth.  She was thoughtful.  She was very emotional.  She was vulnerable. She pushes the edge . . . she pushes the edge a lot, and there's a reason for that."
