Singer Rihanna talks about her life, career and the night her former boyfriend Chris Brown beat her on ABC’s “20/20” at 10 p.m. Friday.

According to a release from ABC News, Rihanna says it was “humiliating” and “traumatizing” to admit the assault took place and that it was “wrong” that she went back to Brown afterwards.

“That’s embarrassing that that’s the type of person that I fell in love with,” Rihanna told Diane Sawyer in her first television interview discussing the assault. “So far in love. So unconditional that I went back. It’s humiliating to say this happened. To accept that? It’s a traumatizing experience.”

Her decision to go back to Brown, she said, was a mistake. “I stayed. I even went back after he beat me, which was wrong,” she said. “But again ... I’m a human being, and people put me on a very unrealistic pedestal. And all these expectations, I’m not perfect.”

The 21-year-old star acknowledged that Brown held her in a headlock twice that night and bit her on the ear and fingers.

After months of silence since the February beating, Rihanna decided to speak publicly about the ordeal so she can be a voice to help others who may be in danger of returning to abuse.

“It’s completely normal to go back. It’s not right. I learned the hard way, but again, this is what I want people to know,” she said. “When I realized that my selfish decision for love could result in some young girl getting killed, I could not be easy with that part. I couldn’t be held responsible for going back.

“Even if Chris never hit me again, who is to say that their boyfriend won’t? Who’s to say that they won’t kill these girls?” she said. “These are young girls, and I just didn’t realize how much of an impact I had on these girls’ lives until that happened.”

After a nine-month hiatus, Rihanna is back on the music scene with a new hit album, “Rated R,” signaling a return from a time of intense loneliness following the assault.

“One of the most lonely times I’ve been was in the past few months because nobody understands what it’s like,” she said. “There are a lot of women who’ve experienced what I did, but not in the public. So it made it really difficult. I just felt like, ‘Oh my God, here it goes, my little bit of privacy.’”

In August, Brown was sentenced to five years of probation, six months of community service and one year of domestic violence counseling for assaulting the 21-year-old pop singer the night before the Grammy Awards.
