On March 25, 2003, Celine began an original three-year commitment to appear five nights a week at The Colosseum at Caesars Palace in Las Vegas, a 4,100-seat arena designed for her show. A 90-minute event, "A New Day..." introduces a new form of entertainment, a fusion of song, performance art, theatrical innovation

and state-of-the-art technology. The show was created by Franco Dragone, the creative spirit behind the acclaimed productions by Cirque du Soleil.
On December 15, 2007 Celine wrapped her four-and-a-half-year residency in Las Vegas, drawing nearly 3 million people to 717 shows, which grossed a staggering nearly USD$400 million in ticket sales. Her show rewrote the Vegas entertainment-rules.
