Rihanna Is 'Fine,' According To Her Grandmother

'I don't want people to worry,' singer's grandmother says.

While rumors swirl surrounding [artist id="1940303"]Rihanna's[/artist] condition following an alleged altercation with [artist id="1961441"]Chris Brown[/artist] over the weekend, the singer's grandmother is speaking out saying she's "fine."

Clara Brathwaite reportedly told Barbadian newspaper Daily Nation Monday that fans shouldn't worry about her granddaughter's health.

"I don't want people to worry," Brathwaite explained. "Rihanna is fine and she is doing well."

The Barbados-born singer's grandmother also shot down speculation that Rihanna endured a broken nose during the spat.

A number of reports, most notably from TMZ, are claiming that Rihanna suffered severe injuries as a result of an argument with Brown, her boyfriend of over a year — though their relationship was in the midst of a rough patch, according to sources. TMZ reported that Rihanna's injuries are "horrific," and include multiple contusions on her face resulting in swelling and bruising, along with alleged bite-marks on her body. The tabloid Web site also indicated the "Umbrella" star suffered a bloody nose and split lip.

Reports of an incident between the singers first broke Sunday night during red-carpet arrivals at the Grammy Awards. Brown and Rihanna got into an argument following a Clive Davis pre-Grammy party on Saturday. The confrontation escalated and the pair were spotted exiting Brown's Lamborghini before a witness called 911.

Brown later turned himself in to the Los Angeles Police Department where he was charged with making criminal threats and then freed on a $50,000 bond.

Representatives for both artists notified Grammy organizers each singer wouldn't be attending the ceremony.

In the aftermath of the altercation, Brown's endorsement deal with Wrigley's has been suspended, and he cancelled an appearance scheduled for this weekend at the NBA All-Star Weekend.

Rihanna also pulled out her concert in Kuala Lumpur, Malaysia. The singer is cooperating with authorities who are investigating the incident. E! reported that a birthday bash set for the Def Jam artist later this month has been canceled by the label.

As of press time, reps for Brown or Rihanna have not commented any further on the matter.
