Carey found her Las Vegas stint, called Mariah Carey's #1 as a brand new stint in her career.

"It's a new chapter for me and I'm just excited about it," the singer said.

The show would be a showcase of her hits compilations, which will be updated and released this year containing her 18 of No.1. songs.

But there's more.... Caesars Palace website also revealed that the five-time Grammy winning will also belt new music.

In a rather delightful note, Carey dressed up as a housekeeper and went around Caesars Palace, surprising guests and handling them free tickets to her show. She also gave away free tickets to Ellen's audience.

The diva will start rocking the stage Wednesday May 6, with shows scheduled every Saturday, Sunday and Wednesday throughout that month. The singer will rest in June and will make a comeback  on July 8 through July 26.

While the show is marketed as a showcase of her unmatched 18 Billboard Hot 100 number ones - she's the only solo act in history to grab that record!- Caesars Palace also confirmed that she will also sing "fan-favorite album cuts," made even more interesting as she sings "never-before-performed selections and many more musical surprises."

News of Carey's Las Vegas debut follows reports that Celine Dion would not be returning to Caesars Palace because she asked for more time off to look after her ailing husband, Rene Angelil.
