According to sources, Cardi B tried to fight Nicki Minaj tonight at the Harper's Bazaar's bash.
"We're told Cardi said, "Let me tell you something" ... as she lunged toward Nicki, but security stopped her inches from contact.
But, Cardi wasn't done ... she pulled off her shoe and threw it at her enemy ... missing her target.
As for Nicki ... we're told cool as a cucumber. She didn't even flinch.
Cardi was escorted out by security, and she left the building with one shoe on her foot.
Now that's fashion!"
Cardi left the event seemingly with a knot on her forehead.
