An official song list and release date are to be announced. The album is expected to coincide with the launch of Carey's Las Vegas residency at The Colosseum at Caesars Palance, which begins May 6.

"I'm going to do my first ever residency in Vegas at Caesars," Carey told Ellen DeGeneres recently. "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. It's a new chapter for me and I'm just excited about it." Check out the cover art PLUS the tweet which morphs #1's cover into #1 To Infinity cover - here.
