In a sneak peek of tonight’s 20/20, Chris Brown tells ‘Good Morning America’ anchor Robin Roberts he never had issues with anger prior to the now infamous February domestic violence incident with Rihanna. As Brown watches clips of Rihanna’s interview with Diane Sawyer last month, he says, “I was wrong for what I did. And I would definitely say it’s not something that I look past or look over. It’s something that’s really touchy. And like I said, I’m really sorry for what went down.”

When Roberts asks whether he understands why people aren’t buying his apologies, Brown says.

“I think what it is when people see me smiling and kind of nonchalantly giving answers or saying things, it’s I’m human,” he says. “Really, I’m like really hurting inside and it really kind of is like devastating to me.” This is Brown’s fourth public apology.
