The Bronx-born rapper met with residents and fans on Thursday evening at the Marlboro Houses in Brooklyn during brisk fall weather.
The crowd - some of which has showed up in the mid afternoon - had reached close to 300 people screaming her name in the street by sunset. "I can't wait to [do] this in my borough next BX", she wrote on Instagram.
Cardi B says she cares a lot about kids and the community and feels it's important to set a good example. "I didn't know it was gonna be so big", she told WABC.
