Rihanna is listless, suffering from headaches and torn"over her parents' pleas to cooperate with police after she was allegedly brutally assaulted by Chris Brown.
"She hums sometimes, but she's more quiet than I've ever seen her," an unnamed pal of the "Umbrella" singer reportedly told a celebrity gossip source.
The friend said Rihanna, 20, visited a doctor last Friday, five days after Brown allegedly roughed her up following a fight in the couple's rented Lamborghini.
"It was because of the endless headaches she's been having since Chris hit her," the friend said. "The doctors were concerned about the contusions on her head."
Reports say that Rihanna - who was said to be furious and unmoved by Brown's apology statement last weekend - is still torn over helping police build a case.

Brown, 19, was arrested the night of the Grammy Awards on suspicion of making criminal threats - he is accused of beating and threatening to kill Rihanna.
Chris Brown is free on $50,000 bail and has not been seen since.
"I mean, damn, her eye's black and the sides of her face are all f----d up," the friend told said. "But she keeps saying she still loves him."
Rihanna's parents are reportedly pleading with her not to worry about how jail time may affect Brown's career, and the Barbados-bred beauty is believed to be cooperating with police, at least for now and to a certain extent.
