TMZ said Rihanna blew the 23-year-old singer-actor a kiss and offered him words of encouragement before they entered the courtroom. She then sat down behind him and his legal team, the celebrity news website said.
The judge overseeing the case said he needed more time to review evidence presented by the district attorney's office and set another court date of April 5.
In the mean time, Brown was to meet with his probation officer within 48 hours to go over allegations he fabricated documentation related to his community service.
Brown was ordered to complete 180 days of community labor as part of his plea deal stemming from his 2009 assault of Rihanna. He was also placed on probation for five years and ordered to attend an anger-management program.
Los Angeles Deputy District Attorney Mary Murray filed a motion this week asking the judge to reject Brown's community service account due to "at best sloppy documentation and at worst fraudulent reporting," the Los Angeles Times said Tuesday.
Prosecutors alleged Brown has provided no "credible, competent or verifiable" evidence he completed any of his court-ordered community labor.
The district attorneys are not asking the judge to find Brown in violation of his probation, but are requesting the recording artist be ordered to complete the work.
Brown and Rihanna recently confirmed they had reconciled after their headline-grabbing altercation.
Brown allegedly has been involved in other physical confrontations since assaulting Rihanna. Singer Frank Ocean told police Brown punched him during an argument over a parking spot outside a Los Angeles-area recording studio last month. Several people associated with both men were allegedly involved but no arrests were made.
Last year, Brown and Canadian singer Drake allegedly were in a fight at a New York nightclub that left eight people injured. No charges were brought in that case either.
JUSTIN BIEBER: Canadian pop star Justin Bieber made history Wednesday by racking up his fifth No. 1 album in the United States before his 19th birthday, which is March 1.
More than 211,000 copies of "Believe Acoustic" have been sold since its Jan. 29 release.
"With this week's incredible success of 'Believe Acoustic,' Justin continues to impress everyone with the magnitude of his artistry," Steve Bartels, president and chief operating officer of Bieber's record label, Island Def Jam Music Group, said in a statement.
"His vision for 'Believe Acoustic' was an organic extension of his growth as a musician on tour and in the studio, consummately devoted to his fans. The album reflects an artist who is not afraid to step outside of every stereotype, regardless of his age. Congratulations, Justin."
BARBARA WALTERS: Ailing broadcast journalist Barbara Walters called in to "The View" Wednesday to say she hopes to be back as co-host of the New York chat show in three weeks.
Walters, 83, was hospitalized last month after she fell and cut her head. She was later diagnosed with the chicken pox. She has been recovering at home for more than a week.
"I have been a little weak. I am not in any pain. And I'm not scratching too much. I'm not itching away," Walters said. "I just feel sort of weak and tired, and I probably won't be back on the program for about three weeks."
'MAMA' JUNE SHANNON: "Mama" June Shannon, one of the stars of the Georgia-set reality show "Here Comes Honey Boo Boo," says she has shed more than 100 pounds in the past two years.
TMZ reported Shannon weighed in at 365 pounds when she first started taping the series in January 2011, but she is now down to 263 pounds.
"I haven't done any surgeries ... no diet pills ... never went to the gym, but, with the show, I've been more active," she told the celebrity news website. "They have me running around and going different places ... I guess it's paying off."
"Here Comes Honey Boo Boo" airs on TLC. It is about Shannon, her daughter, child beauty pageant contestant Alana "Honey Boo Boo" Thompson, and the little girl's father, Mike "Sugar Bear" Thompson.
