Hip-hop star A$AP Rocky is facing an allegation of assault during the Made in America festival in Philadelphia.

The district attorney’s office says a concert-goer claimed the rapper, whose given name is Rakim Mayers, slapped her as he tried to wave away fans while walking through the crowd during Saturday’s show.

The private criminal complaint alleges the 24-year-old Harlem-bred rapper landed an open-palm slap square on the woman’s face, giving her whiplash. The name of the woman who filed the complaint wasn’t released.

A message left at the artiste’s publicity agency was not immediately returned Thursday.
