Rihanna reveals heartache after Chris Brown split

New York, Aug 11 (ANI): Rihanna opened up about her controversial relationship with her former boyfriend Chris Brown to Oprah Winfrey in a candid interview recently.

"It was embarrassing. It was humiliating. I lost my best friend," the New York Daily News quoted her as saying on 'Oprah's Next Chapter'.

She told the talk-show host of how she reacted after the pair split up.

"I was resentful. I held a grudge. I was dark," she said.

Rihanna and Brown, 23, had a very public falling out in 2009 after Brown physically assaulted her on the eve of the Grammys, leaving her black and blue.

However, the pair are reconciled now, after they released two collaborations together earlier this year.

It is also rumored that they have been hooking up "on and off" since their public breakup. (ANI)
