What in the world has gotten into this child?! Here's a video that TMZ got a hold of which features Miley Cyrus (who was 16 at the time) dirty dancing and then giving openly gay 44-year-old, Adam Shankman, a LAP DANCE at the wrap party for "The Last Song".



Gross. Between this and her latest music video for, "Can't Be Tamed", her parents must be just so proud of her.

Although.. I have to admit, I danced the same way when I was her age.. just not up against some old gay man! I also wasn't a teen celebrity role model for young girls. Just sayin'!

Check out Miley on "Dancing with the Stars" Tuesday to see if she behaves herself.
