Chris Brown

R&B star Rihanna is cooperating with investigators building a domestic violence case against her boyfriend, the singer Chris Brown, a police source said Monday. The source said the 20-year-old performer, whose full name is Robyn Rihanna Fenty, was providing "ongoing" cooperation to detectives who booked Brown on Sunday on suspicion of making criminal threats against her.

Until someone dialed 911 on Feb. 8 to report a disturbance in Hancock Park, the pop star Rihanna and her R&B-singer boyfriend, Chris Brown, enjoyed relatively wholesome reputations. Attractive and talented, the couple were known as sexy but not oversexed, fun-loving but not reckless. The two seemed unlikely to be involved in anything more shocking than an all-night dance party. That image opened the door to a host of commercial endorsements.

Los Angeles Police Department officials on Friday were interviewing officers and scouring electronic records amid growing suspicion that someone inside the department leaked or sold to a celebrity website a photo of the singer Rihanna that depicted injuries to her face she suffered during an alleged assault by her boyfriend.

Chris Brown, who is facing felony charges for allegedly attacking his girlfriend, pop singer Rihanna, withdrew Wednesday from Nickelodeon's hugely popular Kids' Choice Awards.

Rocking references that included Run-DMC, Japanese anime, 1950s sock hops and the biggest hit of 2007, Chris Brown rode into the Gibson Amphitheatre on Sunday for the first of his four Southern California concerts on a wave of futuristic nostalgia. Or was it nostalgic futurism?

NORMAN, Okla. -- A matchup between two of the nation's top passers came down to who could run the ball down the stretch. Chris Brown proved to be the man for Oklahoma. Brown ran for three second-half touchdowns, Curtis Lofton returned a fumble for a score and the No. 6 Sooners knocked No. 11 Missouri from the ranks of the unbeaten with a 41-31 victory Saturday night.

Christmas came early to the Baldwin Hills Crenshaw Plaza this year. On a sunny, 75-degree day in October, dozens of aspiring stars from across the Southland gathered there to raise their voices in song, competing in an "American Idol"-inspired contest. Each was asked to perform 60 seconds from either "Silent Night" or the Donny Hathaway R&B favorite "This Christmas" before a panel of "celebrity judges."

About 35 hours into a frenetic three-day swing through the Southland last week, chart-topping R&B phenom Chris Brown was running behind schedule and decidedly low on energy. Uncharacteristically slouched in an overstuffed recliner backstage at the Gibson Amphitheatre, the 17-year-old Virginia native slid the brim of a black baseball cap down over his face, stifling the impulse to yawn. "I'm not tired yet," Brown said, "but I'm getting there."

"I don't do sarcasm anymore," Summer (Rachel Bilson) warns Seth (Adam Brody) on an impromptu trip home to tony Newport Beach from a tree-hugging first few weeks at Brown. "I'm post-ironic." "You mean earnest?" Seth replies in an exchange from the first episode of "The O.C.'s" fourth season (Fox, 9 p.m. Thursday). He's befuddled -- and why wouldn't he be?
