Rihanna said Chris Brown was in a violent trance as he beat her this past spring, in an interview with Good Morning America on Friday.
The 21-year-old Barbadian beauty described, in detail, the brutal beating that took place when she said an argument ensued over a text message Brown received from another woman.
The Disturbia singer said: "I caught him in a lie, and he wouldn't tell the truth -- and I wouldn't drop it."
Rihanna said she recalled thinking during the beating: "When is it going to stop? When is it going to stop? He had no soul in his eyes. Just blank. He was clearly blacked-out. There was no person when I looked at him.
"I couldn't take that he kept lying to me, and he couldn't take that I wouldn't drop it," she said. "It escalated into him being violent towards me. And it was ugly ... I was battered, I was bleeding, I was swollen in my face."
Brown was sentenced to five years' probation and ordered to do 180 days of community labor as a part of the plea deal he made in June for his assault, which took place in in Hancock Park, California. The restraining order issued to Brown orders to keep his distance from her for five years.
