A$AP Rocky got a little confused when he was interviewed by Miley Cyrus’ older sister Brandi at a charity event in New York on Tuesday.

Not realizing who Brandi was, the rapper told her, “You look like Hannah Montana. You ever get that?”

Brandi started laughing and said, “I do get that. Do you wanna know why I get that? Because she’s my little sister.”

“Oh sh*t!” was A$AP Rocky’s response.
