The pop icon arrived to cheering screams at Caesars Palace Monday night 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 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. 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.
