In a mash-up of teasers for an upcoming episode of "Oprah's Next Chapter," the "Where Have You Been" singer can be seen shedding tears when asked questions about Brown -- such as if he's a "true love" and the current status of their relationship.
"It was embarrassing. It was humiliating. I lost my best friend," Rihanna says in the second teaser. She also admits to feeling resentful, dark and once holding a grudge.
Besides her break-up/relationship with Brown, Rih Rih and Oprah cover how the star deals with fame and her love for her hometown of Barbados. The footage feels shockingly open and intimate, considering how tough Rihanna usually appears. Oprah herself even admitted she was "surprised" during her time with Rihanna.
Rihanna's episode of "Oprah's Next Chapter" will air at 9 p.m. on Sunday, Aug. 19. Watch the trailer for the episode above.
