We've seen apology videos and statements from Chris Brown over the past few months, but we haven't heard much from Rihanna about what happened in February between them. But in a 20/20 interview airing tonight, RiRi reveals a lot about what went down on Grammy night. All she kept thinking was, "When is it going to stop? He had no soul in his eyes. Just blank," she says in the interview, according to People. The fight, she says, escalated when she confronted him about a text he received from another girl. "I couldn't take that he kept lying to me, and he couldn't take that I wouldn't drop it... It escalated into him being violent towards me. And it was ugly." She also now admits that their relationship was unhealthy. "The more in love we became, the more dangerous we became for each other, because it was a bit of an obsession."
