A video of Miley, 17, obtained by TMZ, shows her dancing with Shankman, 44, during a wrap party last summer for their film, "The Last Song." The Disney star's dirty dance moves were reportedly so inappropriate, some of the parents who attended the party left early with their children.
At one point in the video, Cyrus turns toward Shankman and opens the top layer of her shirt, teasing him with her flirty dance moves.
The producer -- who is openly gay -- defended the "Hannah Montana" star on Twitter last year. "Miley is a sweet angel who works tirelessly and endlessly, and is allowed to have fun in the makeup room," Shankman said about photos he posted of her on Twitter. "Lighten up, or no more behind-the-scenes pics! She is my angel sister."
What do you think of the lap dance video -- bigtime no-no, or no big deal?
