2. Celine Dion
When Celine Dion started her first Las Vegas residency show in 2003, many were uncertain if the French-Canadian star would be able to entertain the crowds in Sin City. To the surprise of many, the show ran for five years. Celine made a comeback in 2011 with a new show titled Celine that was another huge success. Her shows incorporated Cirque-style acrobats, dancing, dazzling video work, and a lavish orchestra. So far, she has performed over 1140 concerts and continues to grace the stage with her beautiful voice.
