LAS VEGAS - Mariah Carey arrived to cheering screams at Caesars Palace Tuesday in a classic 1936 pink convertible trailing behind 18 mobile billboards bearing the titles of her number one hits including “Always be my baby” from 1996 and “Heartbreaker” from 1999. The gladiator-clad men took it from there, carrying Carey through the casino on a platform fit for Cleopatra. The grand entrance marked her Las Vegas Strip arrival that will bring her chart-topping hits to The Colosseum at Caesars Palace starting May 6 with performances through July. Called “Mariah #1 to Infinity,” the show is timed with the debut of Carey's newest breakup single and music video dubbed “Infinity.” Carey sang along to the new song on a stage inside, at one point filming herself and the crowd with an iPhone. “I can't wait to sing all the hits for you guys,” she told the crowd. The Grammy winner is among the best-selling female solo artists of all time and joins the ranks of Celine Dion, Elton John, Rod Stewart and Shania Twain, who have all taken up residency at The Colosseum. - AP
