Celine Dion is more of a pop star than a rock star, I'd say. She sang the theme song from "Titanic." Also won an Academy Award for singing the title song in Disney's animated "Beauty and the Beast." Sang at the opening of the Olympics in Atlanta. Is probably the greatest superstar ever to come out of Canada. She was married in December 1994 and I imagine a chip from her wedding, if authenticated, would fetch more from a fan of the diva's than a casino chip collector.
