The night Chris Brown beat Rihanna bloody he had "no soul in his eyes".

Rihanna opened up more in her emotional interview with Diane Sawyer about the night her world stopped when  ther hen BF beat her senseless after a pre-Grammy party.

Rihanna finally confirmed what the ENQUIRER first reported  – that she saw a booty call text message on his cell and became incensed.

"I caught him in a lie and he wouldn’t tell the truth. So… I wouldn’t drop it," Rihanna said.

"I couldn’t take that he kept lying to me and he couldn’t take that I wouldn’t drop it – because, obviously, his back is against the wall.

"The truth is right here with the text message. So it escalated into him being violent towards me – and it was ugly."

He then began bashing her in the face with his hamhock fists – so many times her mouth swelled with crimson.

"All I could think the whole time — When is it going to stop?

"He had no soul in his eyes. Just blank. "There was no person when I looked at him."
