On January 15, 2015, Carey appeared on The Ellen DeGeneres Show to announce that she signed a contract to take up residency at The Colosseum at the Caesars Palace hotel in Las Vegas in May and July 2015; it is called Mariah Carey #1's. During the interview, Carey confirmed "I'm going to do my first ever residency in Vegas at Caesars." "This is a special event for me. And again, I have to hope that the fans will enjoy this cause I'm gonna be performing, which was kind of inspired by my album #1's, and this is now the updated version with eighteen of them. Hopefully other people will enjoy this. I've never done this before." The confirmation of Carey's residency came after Canadian singer Celine Dion announced that she has postponed dates of her residency at Caesars Palace to care for her husband, René Angélil, who is suffering from cancer. In March 2015, Dion confirmed that she will return to Caesars Palace in August to continue her residency following the departure of Carey.
