According to RadarOnline.com, the tape shows Cyrus, 17, giving Shankman, 45, a risque lap dance during their film"s wrap party last year.
“The video was taken about seven months ago at a wrap party for The Last Song," the New York Daily News quoted a source as saying. “The worst part is that there were little kids at the party and the dancing between Miley and Adam was so dirty that some of the parents actually left the party and took their kids home," the source said.
The video reportedly shows Shankman, an openly gay man, with a drink in hand as he grinds up against Cyrus" backside on the dance floor, while she grinds back as well. The Disney star, then 16, then turns around and seductively opens the top layer of her shirt, teasing Shankman with her flirty dance moves.
