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 #1 to Infinity. 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 megastar Celine Dion announced that she had postponed dates of her residency at Caesars Palace to care for her husband, René Angélil, who was suffering from cancer. Aside from singing "Infinity" at her residency, Carey performed a medley of her 1990 debut single "Vision of Love" followed by "Infinity" at the "Billboard" Music Awards on May 17, 2015; it was her first performance at the ceremony in seventeen years. Andrew Hampp for "Billboard" described the performance as "octave-leaping" and one of the most memorable of the night. Other promotional appearances included "Jimmy Kimmel Live!" and "Live! with Kelly and Michael". For the latter, Carey wore an Aurora-inspired dress from the Disney film "Sleeping Beauty" and performed on Main Street, U.S.A. in Disney World.
