Singer Leona Lewis sparked Rihanna row

The argument between Brown and Rihanna became so violent that he allegedly attacked his girlfriend and gave her a swollen face,’The Mirror’ reported.

Brown was seen speaking to Lewis at a pre-Grammy awards party in Los Angeles.

“Rihanna saw Chris flirting. He and Leona were laughing and Rihanna saw his hand on the small of her back. It was totally innocent but it set Rihanna off,” a source told the newspaper.

Police sources said the ‘Umbrella’ singer lost consciousness as Brown screamed at her “I’m going to kill you”.

Since the alleged attack,Rihanna has been hiding and cancelled her second concert in Jakarta.

The singer’s grandmother Clara Braithwaite reassured fans yesterday,”I don’t want people to worry. Rihanna is fine and she is doing well”.
