Chris Brown “lost everything” when he lost Rihanna, the singer said Monday morning.

Trying to show a softer, humbler side to win back public esteem and promote his “X” album, the R&B singer sat down with "Today’s” Matt Lauer.

It's been nearly four years since Brown's domestic abuse incident with on-again, off-again girlfriend Rihanna, and although she has forgiven her lover his faults, the public generally has a lingering distaste for him.

"I've been humbled by the whole experience," Brown, 23, told Lauer in an interview quoted by ETonline.com. "From me losing everything, you know, to me having to regain public opinion or whatever it is -- but most importantly, you know, knowing that what I did was totally wrong and having to kind of deal with myself and kind of forgive myself in the same breath and being able to apologize to, you know, Rihanna and be that man that can be who is a man, you know?"

The “Today” anchor proceeded to call out Brown's argumentative behavior. Brown’s been known to start Twitter battles with fellow music celebs like Frank Ocean and Drake.

"I think everybody is entitled to their opinion," Brown replied. "For me, it's just a learning process. You know, I have to just take it one day at a time. I can't make everybody like me. ... It's about me being positive."

He asserted that “everything is good” with Rihanna now, and he is ready to face the doubts of the public.

"I think it's just me proving myself once again," Brown said. "Knowing that what I did was wrong, and never doing it again. So as far as me and her are concerned, she knows my heart, and I know her heart. So I'm not really focused on the negative."

Brown and Rihanna started dating when they were both young teenagers who had just burst onto the music scene, but their fairy tale romance was tarnished when Brown assaulted the Barbadian beauty in 2009, leaving her face bruised and bloody the night before the Grammy Awards.

Photos of the violent incident went public, and both Rihanna and Brown entered “dark” places when they were apart from one another.

The lovers recently announced they had gotten back together, but not without criticism from almost anyone who had heard of the couple’s troubled past.

Rihanna told Oprah Winfrey last year that Brown was “the love of her life” and explained to Rolling Stone magazine during an interview that she could handle the criticms of the public; all that matters is that she’s happy when with him.

Celebrity blogger Perez Hilton recently reported the two would be getting married in July in Rihanna’s home country of Barbados.

No date has been revealed for the couple’s supposed nuptials.
