The pop superstar made a grand entrance in Sin City on Monday (27Apr15) to celebrate the start of her Mariah #1 to Infinity shows at the casino's The Colosseum venue next month (May15).

Carey arrived in a pink car behind 18 billboards emblazoned with the names of her number one songs, and she then climbed onto a red velvet recliner to be carried into the resort by hunky performers.

The singer documented the event in a series of photographs on her page, and added in a caption, "Festivity!!! Thank you for such an amazing welcome. See you at the shows!!!! #1toInfinity."

The shows begin on 6 May (15) and run until July (15).
