20-year-old singer Rihanna, who sustained injures during a Pre-Grammy Awards fight with her 19-year-old boyfriend Chris Brown, is now out of the hospital, according to online reports.

LAPD officers, who interviewed the Barbadian beauty in the hospital, say she sustained violent trauma to her face and body, including bite marks on her arms and fingers, contusions, swelling, bruising and a bloody nose.

Rihanna may have inflicted similar damage on Brown as they fought inside and outside his rented Lamborghini near Hancock Park in LA early Sunday morning.

Witnesses heard her screaming and called 911. Brown fled the scene on foot and later turned himself in accompanied by famed attorney Mark Geragos who once repped Michael Jackson, among other notables.

Rihanna’s reps say her upcoming 21st birthday bash on Feb. 20 in NY is canceled. And a Malaysian concert is also scrapped as well as appearances at the upcoming NBA All-Star weekend in Phoenix.

The backlash against Brown has already begun. He was unceremoniously dropped from the Wrigley’s gum campaign Monday. And Brown’s reps say an upcoming gig in Phoenix is canceled.

The reaction from the industry was swift as well. According to a tipster, Rihanna’s brother would love to put his hands on Brown, and other men in the industry would like to “touch” him as well.

Rihanna has made many friends in the industry who reached out to her with offers of protection in the 24 hours since the incident.

Brown’s next court date is on March 5th. He is charged with making terroristic threats against Rihanna, who may not be willing to testify against him in open court.

There are rumors that Rihanna and Chris fought like cats and dogs behind closed doors and their handlers knew that eventually the violence would spill out into the open.

It seems the two were obsessed with each other, according to friends. It was the type of obsession that usually leads to violence. One source who is close to both camps told Sandrarose.com how Brown pursued Rihanna and how badly he wanted her before the two ever met.

“Rihanna paid that boy no attention for months,” said my source. “Then she finally gave him a chance and realized he was really cool [to be with].”

Brown’s mom, who has friends in Atlanta, is already defending her son and telling what she knows about prior incidents involving the couple. If you recall, it was Brown’s mom who spilled the beans to friends about Brown’s sordid relationship with his much older manager — a relationship that the manager vehemently denied.

Still, questions remain whether Rihanna was the aggressor in the current incident and if she struck out at Brown first, forcing him to defend himself.
