A$Ap Rocky was left embarrassed after telling Miley Cyrus' older sister Brandi that she looked like the singer's former Tv persona, Hannah Montana.

The Wrecking Ball hitmaker's 26-year-old sibling served as a correspondent for U.S. Tv network Fuse during a charity event on Tuesday (10Dec13), and while on the red carpet, Rocky noticed that his interviewer looked familiar.

He suggested, "You look like Hannah Montana. You ever get that?"

Brandi began laughing and said, "I do get that. Do you wanna know why I get that? Because she's my little sister."

A stunned Rocky exclaimed, "Oh s**t. I feel like a complete total a**hole! I know who you are now, my bad. I didn't even say Miley - I said Hannah... But you look better."
