Wow! The next time Rihanna is cast in a film, and you wonder why, this might help explain it.

Her interview with Oprah Winfrey on Sunday was OWN network's 2nd-highest rated broadcast ever, attracting 2.5 million viewers!

And what was the network's highest-rated broadcast? Oprah's sit-down with the late Whitney Houston's family.

With that, the Rihanna episode of Oprah's Next Chapter, won its time-slot in its demographics – women 25-54, and women 18-49.

After what was a challenging first year on the air, the Oprah Winfrey Network (OWN) has seen some of its best ratings yet, thanks to recent sit-downs with public figures. So does that mean Oprah might/should return to the format that made her popular in the first place?

I say expect many more of these sit-downs with popular celebs.

But clearly Rihanna is a draw, whether you love her, hate her, or just don't care. And I'd guess that pre-broadcast ads for the episode revealing that she would be talking about Chris Brown, may have helped attract some extra eyeballs and ears.

Did you watch? I didn't.
