It's official: Miley Cyrus is a horrible role model! Not only did Miley drop jaws when she did a pole dance number at the Teen Choice Awards on stage, she's now teaching her nine year old sister how to dirty dance. Um... she's nine!

Miley can be seen in a video clip urging her younger sister Noah Cyrus to perform a routine to Akon’s ‘Smack That’ featuring daring shimmies and pats to her butt.

Check out the clip below and you tell us...innappropriate or just kids having fun??
