Rihanna has been playing the part of a good girl gone bad for the past 4 years now, but is that who she really is at her core?

She curses like a sailor on Twitter, posts risque photos of herself and regularly finds herself in the middle of drama and beef between men … but according to Oprah Winfrey, Rihanna’s just a regular, sweet, down-to-earth island girl.

Oprah visited Rihanna on her home island of Barbados to film an interview with the pop star for her OWN network.

Mama O initially thought that she’d be meeting with the middle-finger flashing, weed rolling girl who runs wild on all the blogs, but she found a polite, subdued, easy going Robyn instead.

Something tells us that Rihanna’s putting on a good show cause she wants a little bit of an image makeover.

She’s kind of pushed the bad girl thing to the limit. So much so that Nivea has dropped her from future endorsements.

But it does appear that Mama O asks some real questions, cause she gets RiRi to tear up at one point.

Check out this preview of Oprah’s interview with Rihanna below:

The big question: Is she gonna ‘go there’ with Rihanna about the Chris Brown thing?

Oprah went in on the issue back in 2009, saying, “Love doesn’t hurt. And if a man hits you once, he will hit you again.”

So you can imagine that Oprah might feel a way or two about Rihanna teaming up with Chris for that “Birthday Cake” remix.

The full interview with Rihanna and Oprah is set to air next Sunday on Aug. 19 at 9 pm Eastern.
