New York – Pop icon Mariah Carey will open a series of shows May 16 at The Colosseum in Las Vegas. Caesars Palace and Carey have announced 18 performances, so far. The show, dubbed Mariah Carey #1s, will feature the singer performing her 18 No. 1 singles, including We Belong Together, Hero and Vision of Love.
