Mariah Carey wanted Las Vegas to know there's a new girl in town.

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 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.

Devin Cole, 28, can't wait to hear them. The Queens resident with a Carey collage on his phone hopped a flight to Las Vegas for the weekend when he heard about the Caesars event. Cole credited Carey's songs for keeping him alive as he battled depression at 16 years old.

"She's a lyrical goddess," he said.

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. Across the Strip, pop star Britney Spears calls a Planet Hollywood stage home.

Tickets for Carey's show are priced from $55 to $250.
