Banks had just started her set at the Listen Out Festival in Melbourne, Australia, when the can came sailing her way.
The 22-year-old star wasn't hit, but she was mad enough to drop her mic, mid-song, and walk off stage.
The festival confirmed the incident in a statement.
"Azealia Banks was forced to cut her set short last night at the Listen Out Festival in Melbourne on 5th October 2013," the statement said. "This was as a result of a member of the audience throwing a full can of beer at her on stage. The incident made Azealia and her stage crew feel unsafe. Banks would like to apologize to those fans in the audience whose experience was affected by the behavior of one individual."
Fortunately, the show Sunday in Brisbane went as planned.

K. Brisbane went smoothly. No one threw any cans at my head. I'm gonna read my Cat encyclopedia, have a wine and go to sleep.— AZEALIA BANKS (@AZEALIABANKS) October 6, 2013
