Noah Cyrus Smacks That, All On the Floor

Sorry, Miley Cyrus supporters. But you can no longer wonder why your role model was named the Worst Celebrity Influence of 2009.

After all, she's apparently been showing little sister Noah Cyrus just what she and Liam Hemsworth do in the bedroom.

Backstage at a concert this week, Miley and a few dancers whooped and hollered in encouragement as the nine-year old danced to Akon's "Smack That" and sung lyrics that include:

Smack that, all on the floor
Smack that, give me some more
Smack that, 'til you get sore
Smack that, oh ooh

Watch below, as Noah possibly gets bent over, looks back and sees her older sister cheering on her inappropriate antics:

Smacking That

Remember Noah's Halloween outfit, too? The Cyrus family has this tyke primed to pose for Playboy and/or sleep with Tiger Woods as soon as she turns 18.

Shame on them.
