Los Angeles, April 14 (IANS): Singer Mariah Carey has officially announced her new album "#1 to Infinity", which will accompany her Las Vegas residency.

A few days ago, Carey set a countdown that ended on Sunday, with the revelation of the record's artwork, reports aceshowbiz.com.

A re-issue of her greatest hits collection "#1", the upcoming project still has no release date. Its cover art features a photograph of Carey flaunting her cleavage and her long legs in a mini black dress teamed with a pair of black heels.

"#1 to Infinity" will feature all 18 of her chart-topping hits as well as newly-recorded music.

Carey's Las Vegas residency is scheduled to start on May 6 at The Colosseum at Caesars Palace. While gearing up for the forthcoming shows, earlier she split from her longtime publicist Cindi Berger and replaced her with Chris Chambers. She also hired TV producers Brian Sher and Stella Bulochnikov to serve as her new managers.
