Mariah announced the news on “The Ellen DeGeneres Show,” where she surprised the studio audience with tickets to her show and a hotel stay at Caesars Palace.

“I have so many ideas for the show that I’m currently working on and am excited to perform all of my #1 singles together for the first time and others that are very close to my heart,” said Mariah. “My songs are the soundtrack of my life and I can’t wait to share them with my fans on stage!”

In conjunction with the concert series, Mariah is working on a new edition of her 1998 album #1’s, which will include all 18 of her chart-topping hits as well as newly-recorded music. The album will be released later this year.
