Cardi B ripped the NYPD for getting her friend Star's back to school event in Brooklyn cancelled.

The "Money" rapper claimed New York police called the school's principal and scared him into backing out of the event, which Star paid for out of her own pocket.

"This is really for the kids," said Cardi, who was recently sued for copyright infringement. "It was for kids to have a fun, positive day. You know, to benefit the parents with school supplies and many more things. And I just find that sh*t so f*cked up, and f*uck you and motherf*ckin' suck a fart and suffocate on it. "F*ck you."
