LOS ANGELES - R & b singer Rihanna broke her silence yesterday about the night her ex-boyfriend Chris Brown attacked her, saying he had bitten her, put her in a headlock and left her bleeding and swollen.

“It wasn’t the same person that says ‘I love you.’ It was not those . . . eyes,” Rihanna, 21, told Diane Sawyer in an interview on ABC television’s “Good Morning America” show.

“He had . . . no soul in his eyes. Just blank. . . He was clearly blacked out. There was no person when I looked at him,” she said.

Brown, 20, singer of hits such as “Kiss, Kiss,” was sentenced to five years probation and 180 hours of community service for the assault in February on the eve of the Grammy Awards .

He has apologized publicly and although the pair briefly reunited, Rihanna said she now has “no desire at all to be with him.”

Rihanna said the attacks started with an argument over a text message Brown received while they were driving home from an industry party.

She acknowledged police reports that Brown bit her, put her in a headlock until she had trouble breathing and punched her several times in the eye.
