Chris Brown is being accused of living up to his bad-boy reputation.

E! News has learned that 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.

UPDATE: Heat management is standing by Brown, with Mike Joher of Royal Entertainment telling E! News in a statement that, based on information gathered from their security, mall security and other partygoers, "it is apparent that the alleged incident regarding Chris Brown is fales."

According to the club, Brown's accuser was trying to jump on the stage and "there was no way that he could have touched her, his section was roped off and he had heavy security surrounding him. Witnesses state that she was persistently trying to rush Chris" and was "eventually removed from the club."

Heat also alleges that the woman threw her shoes at club security as she was being escorted out and, while they thought about calling the cops, they allowed her to just leave.

Brown "was a complete gentleman and remained professional throughout the entire night," Joher concluded. "Neither I, nor any of the witnesses we spoke to, saw him push or touch anybody."
