Rihanna And Chris Brown

A source has revealed to PEOPLE magazine that the late night fight between Chris Brown and Rihanna last weekend left plenty of evidence of the violence.

“Chris knocked her around,” a source close to the couple told PEOPLE. “Black eye, blood, bruises. She had to be treated by a doctor.”

Police have confirmed that Rihanna suffered a black eye as well as a swollen, split lip and two red and purple contusions on either side of her forehead.

The source, who described police photos of Rihanna, added, “She looked distraught and in a lot of pain. Her eyes were closed because she was looking down.”

Rihanna was discharged from Los Angeles’ Cedars-Sinai Medical Center Monday night, a source close to the investigation told E! News. A decoy distracted photographers while the singer was escorted out the back door, the site said.

She is in “a safe place,” according to another friend and is cooperating with police.
