Miley Cyrus' Sister, 9, Sings About Beer, Being "Crunk"

Miley Cyrus' 9-year-old sister Noah -- who turned heads in a dominatrix Halloween costume and recently covered Akon's racy tune "Smack That" -- is at it again.

In a new YouTube video, she covers Ke$ha's hit "TiK ToK."

As a bearded person in glasses and a hoodie dances behind her, she prances around in front of the camera.

At one point, she tosses what appears to be a can of Red Bull as she sings the line: "Ain't got a care in the world but got plenty of beer."

Oh yeah, she also lip-syncs lyrics about smacking men who touch her junk.
