Chris Brown is under investigation for battery after allegedly smacking a woman so hard that he dislodged part of her hair weave.
Police responded to an assault call at the singer's San Fernando Valley home over the weekend after a woman's allegation that he hit her.
Law enforcement sources told TMZ.com the woman claimed Brown smacked her on the back of the head so hard that part of her hair weave fell off.
However, police evaluated the woman and determined she had no injuries, and no arrests were made.
Police took a battery report following the alleged incident, which may result in a misdemeanor charge against Brown.
Brown and his representatives have yet to comment on the allegations.
It's the second time in as many months that police have been called to Brown's house - the first was in May when the Los Angeles Police Department responded to noise disturbance calls at a huge birthday bash. Police broke up the party in the early hours of the morning, and no arrests were made.
