has opened up about his infamous attack on , calling it a “mistake” and the “deepest regret” of his life.
The 23-year-old singer, who left the "Diamonds" hit-maker bruised and battered after physically assaulting her in 2009, also said that the pair is now back together and he would never hurt Rihanna again.
Speaking to British tabloid The Mirror, Chris said: “That night was the deepest regret of my life, the biggest mistake.”
The R&B star claimed that he had to work hard to get Rihanna's forgiveness.
“But she loves me – what can I say? I’m forgiven… but, yes, I worked hard for it,” he added.
Brown went on to suggest that the couple had put the incident behind them and are now back together even though people still haven’t forgiven him.
“Sometimes you row, you fight, with the one you love and things get said, stuff spirals,” he told the publication.
The "Don’t Wake Me Up" singer had to face a severe public backlash after he attacked Rihanna during an argument back in 2009 following a pre-Grammys party. He was sentenced to five-year probation and six months of community service after admitting to the assault in court.
However, the couple has since reconciled and reportedly holidayed together in Hawaii last week to celebrate Rihanna’s 25th birthday.
This week, he gushed to The New York Post at the Oscars: “We are really happy. We are back together. She is the most beautiful girl in the world.”
“But I’m sad she couldn’t be here tonight. She is rehearsing for her tour,” he added.
Nonetheless, the pair is now facing a fresh onslaught from the public in general and domestic abuse campaigners in particular.
Brown, who was spotted on Monday at Elton John's Oscar party without Rihanna, paid no attention to host Seth MacFarlane's joke about him during the star-studded ceremony.
After he introduced Quentin Tarantino's blockbuster, “Django Unchained,” MacFarlane mocked the pair by comparing the violence of the revenge film to “date night” for the couple.
He joked that it was “the story of a man fighting to get back his woman, who's been subjected to unthinkable violence - or as Chris Brown and Rihanna call it, a date movie.”
The reference to the 2009 incident drew audible gasps from the audience in Hollywood's Dolby Theatre. But speaking to The Mirror, Chris said he wouldn’t let the criticism get to him.
He explained: “People attack me and criticize me, it happens all the time. But they don’t know me, and they don’t know us. It doesn’t bother me anymore. Other people can judge us but they don’t know anything.”
