Tonight’s the night for Mariah Carey.

In a mere matter of hours, the superstar’s Las Vegas residency ‘Mariah #1 To Infinity’ launches live from The Colosseum at Caesars Palace. 

Initially booked for a three month run, expectations are high for the diva’s stint, which  sees her perform all 18 of her US #1 singles in chronological order.

So as to whet appetites even more, Mimi took Good Morning America‘s Michael Strahan on a tour of the backstage area of the show.

All is looking good. Let’s hope it sounds it too.
