NEW YORK - Mariah Carey is heading to Sin City.

Caesars Palace announced Thursday that the pop icon would open a series of shows May 16 at The Colosseum in Las Vegas. Carey has announced 18 performances, so far.

The show, dubbed "MARIAH CAREY .1s," will feature the singer performing her 18 No. 1 singles, which includes "We Belong Together," "Hero" and "Vision of Love."

Carey's announcement comes after company lawyers said Wednesday that a division of financially troubled Caesars Entertainment Corp. will head to court in Chicago on Thursday to file for Chapter 11 bankruptcy protection.

Tickets for Carey's show range from $55 to $250.

Carey, 44, is following in the steps of Britney Spears, Celine Dion and Shania Twain, who have performed their worldwide hits at Vegas residences.
