Rapper A$AP Rocky, who's known for slapping female fans in the past, has been slapped with an assault charge in Philadelphia after allegedly slapping a female fan this past weekend.

According to reports:

"The alleged victim, a young mom, filed a criminal complaint with the District Attorney's Office today claiming she was attending the Made In America concert on Saturday when the rapper got violent.

The woman claims A$AP was trying to make his way through a crowd of dancing fans -- with a bunch of girls pulling on his shirt -- when A$AP turned and fired off an open-hand slap, connecting with her face."

The woman claims she was injured from the alleged slap -- suffering whiplash from the impact. The D.A.'s office reviewed the case and has decided to charge A$AP with misdemeanor simple assault.

Rocky has not yet responded to the accusations.
