Leave it to Cardi B to bring a little heat to the NPR Tiny Desk … because she set the mic on fire with her stripped-down set … and it’s all on video.

The rapper banged out 8 of her hottest hits in under 20 minutes, and she looked like she was having a blast the whole time.

Cardi performed smash hits like “Up” and “Bodak Yellow” … before closing out the stellar set with her chart-topper “I Like It.”

She looked great behind the tiny desk … belting out her tunes in black leather pants and a blazer.

Cardi had a full-on band packed into a small space … we’re talking bass, piano, guitar, drums, saxophone, trumpet, and some background vocalists … but, as always, she stole the show.
