A video of a dirty dancing Miley Cyrus, taken during the wrap party for her latest movie release, 'The Last Song', has been leaked. According to RadarOnline.com, the video appears to be a kind of follow up to several provocative pictures of Cyrus posted last year where she was seen giving a lap dance to 'The Last Song's' producer, the openly-gay Adam Shankman.

The celebrity news site reports that the video, of which they have seen, shows Shankman on the dance floor with a drink in hand grinding up against Cyrus' backside while she reciprocates the action. Later in the video, Cyrus turns around and seductively opens the top layer of her shirt, supposedly teasing the producer with some flirty dance moves.

A second clip of the video depicts Cyrus, who will only turn 18 in November, giving a lap dance to Shankman while children of no more than 10-years-old were sitting and watching the Disney starlet nearby. A source revealed that as "the dancing between Miley and Adam was so dirty ... some of the parents actually left the party and took their kids home."

Cyrus' parents, Tish and 'Achy Breaky Heart' singer Billy Ray, were not present at the bash but has insisted that he did not see a problem with her actions and "it's what people her age do". The pop princess' off-screen, and on-screen, lover, Liam Hemsworth has also defended his girlfriend, stating that "everyone gets criticism, it's kind of what comes with this job ... everybody's trying to bring you down. She's got a good head on her shoulders."

Just a few weeks ago, Cyrus was seen desperately trying to break out of her good girl, Hannah Montana image with the release of her latest video, 'Can't Be Tamed'. Many critics have noted the strong sexual appeal Cyrus attempts to exude in the video where in it, Cyrus plays the role of a metaphorical songbird trying to break free from being caged by her previous image and the outside world.
