Charge against Chris Brown dropped

Friends since 2005, Chris Brown and Rihanna went public with their romantic relationship in 2008. The couple went their separate ways after Brown pleaded guilty in June 2009 to assaulting the Barbadian singer on the eve of the 51st Grammy Awards. They've since reconciled, only to seemingly break up again. Here's a look back at their rocky relationship:

In December 2008, Brown and Rihanna performed onstage during Z100's Jingle Ball in New York.

Brown stood beside his lawyer, Mark Geragos, at court in Los Angeles in March 2009. Brown was charged with assaulting Rihanna on February 8. "I'm in shock, because, first of all, that's not who I am as a person, and that's not who I promise I want to be," Brown told Larry King in August 2009.

Months after the incident, Rihanna left a preliminary hearing at court in Los Angeles in June 2009. "We just fell really fast, and the more in love we became, the more dangerous we became for each other -- equally as dangerous -- because it was a bit of an obsession," Rihanna said during a 2009 interview with Diane Sawyer.

In June 2010, Brown performed a tribute to Michael Jackson during the BET Awards in Los Angeles. After Brown pleaded guilty to assaulting Rihanna, a restraining order mandated that the pair cut off communication and remain a certain distance apart.

The "Birthday Cake" singer opened up to Oprah about the night that changed everything between her and Brown during an August 2012 interview. "I lost my best friend," she said. "Everything I knew switched -- switched in a night -- and I couldn't control that, so I had to deal with that, and that's not easy for me to understand."

In 2012, the pair shocked onlookers when they cozied up to one another at a Lakers game on Christmas.

Rihanna opened up to Rolling Stone about her repaired relationship with Brown in the magazine's February 1 issue, and by February 6, the pair were seen cruising in Brown's car.

And by the Grammy Awards two weeks later, the pair were seen cuddling in the audience.

The rumors about the pair's romantic status heated up around Rihanna's 25th birthday in late February when the two were seen vacationing together.

Although Rihanna's infamous for sharing cozy photos of herself with Brown on Instagram, he clarified in early May 2013 that they weren't a couple. "[A]t the end of the day, shawty doing her own thang, she on the road. It's always gonna be love. I'm a grown man, just gotta fast forward," he told an Australian radio station. "I'm always gonna love that person. I can't be focused on wife-ing someone that young. I need to be the best Chris Brown I can be."

Brown, 24, has been in legal hot water since February 2009 when he was charged with domestic violence after beating his then-girlfriend, Rihanna.

In addition to the probation revocation triggered by the traffic incident this summer, the Los Angeles County district attorney has accused Brown of violating probation by fraudulently reporting that he had completed the community labor ordered as part of his sentence for beating Rihanna.

Brown is set to be in court Friday for the judge to set a date for a probation revocation trial, which could send him to jail.

Geragos said the driver who accused Brown after a traffic accident in May did not get any money in her settlement with his client.

"She did not want to pursue this," he said. "She did not understand that this could even be a criminal matter and said she didn't want to pursue criminal charges."

The city attorney who was prosecuting the case objected to the compromise because of Brown's felony probation status and his allegedly aggressive behavior in the incident.

Olga Gure told investigators that after Brown's Range Rover rear-ended her Mercedes on a Los Angeles street, he "went ballistic" and screamed at her.

Gure said Brown shouted at her: "You are a b---h!"

The report added more from Gure, who quoted Brown as saying, "Who do you think you are, b---h? Do you think if you driving Mercedes so got money, b---h? Do you think I am just a black n----r? I got more money than you, beech!"

The trigger for Brown's alleged rage was that Gure took a photo of him and his girlfriend, Karrueche Tran, to document the scene because he allegedly refused to show her his driver's license, she said.

When Brown tried to grab the camera, Tran screamed, "Don't touch her, don't touch her," Gure said.

"I was so shocked that I was speechless," she said, according to the report. "Just a moment ago he was a nice guy. After screaming some insulting nonsense for a while longer, he slammed a door and drove away, fast and noisy."

Brown was ordered to return to court on Friday for a hearing to set a trial date to determine if the probation revocation will stand. If it does, Los Angeles County Superior Court Judge James Brandlin could order Brown to jail to serve part of the original five-year jail sentence imposed for the attack on Rihanna.

Brown punched Rihanna inside a rented Lamborghini on a Hollywood street, leaving her face bruised and bloody on the eve of the Grammy Awards in February 2009.

He entered a guilty plea seven months later and was sentenced to serve five years probation and to spend more than 1,400 hours in "labor-oriented service" for the assault conviction. The judge allowed him to serve the sentence in Richmond, Virginia, under the direct supervision of the police chief.

In a court filing in February, prosecutors accused Brown of not completing the community labor. The paperwork Brown submitted to show he had completed community labor is "at best sloppy documentation and at worst fraudulent reporting," District Attorney Jackie Lacey said. Brown wasn't in town on some of the dates reported, the motion said.
