Chris Brown Accused of Assaulting Another Woman in California, He and Girlfriend Karrueche Tran Seen In Intimate Picture Amid Reports of Brown's Hard-Partying. Is Rihanna Dropping Plans to Collaborate With Him? Friends Are Worried About Him.

Chris Brown is being accused again of assaulting a woman, this time in California. Reportedly, Rihanna is livid with him and his friends are worried about his lack of control.

According to E! News, the singer has been accused of assaulting a woman at a San Diego nightclub on Saturday evening.

The Anaheim Police Department confirmed that they received a phone call from a woman alleging that she was pushed by the rapper during his performance at Heat Ultra Lounge at 9:30 p.m. on Sunday night.

She claimed that she was pushed and injured, but did not meet with the police in person regarding the incident.

The investigation is currently ongoing, and police have not revealed the identity of the woman involved in the alleged incident.

E! News exclusively spoke with the operational manager at the nightclub who claimed to hear that Brown had "moved someone out of the way" after his set and that "perhaps the incident is being blown out of proportion."

Brown, apparently responding to reports of the incident, tweeted, "I didn't do anything." His tweet has since been deleted.

Earlier this month, the "Fine China" singer was in court to discuss discovery materials stemming from his 2009 assault case.

The L.A. County District Attorney's Office had accused the Grammy winner of providing shoddy documentation concerning the 180 hours of community labor he supposedly completed as part of his sentence for assaulting Rihanna.

Per the current terms of his sentence, he is on probation until next summer. The judge set a preliminary hearing date for July 15 to determine whether they should move forward with a probation-violation charge.

No word yet on how the latest assault allegations may affect Brown's ongoing court case.
