TMZ has obtained a video reportedly filmed last summer that shows a 16-year-old Cyrus grinding on the dance floor and later giving 45-year-old So You Think You Can Dance judge Adam Shankman a lap dance. The video was reportedly taken during the wrap party for Cyrus' movie, The Last Song. Shankman, who is openly gay, produced the film.
