After recently splitting with her publicist of over 15 years, Mariah Carey has appointed Chris Chambers at The Chamber Group to handle her publicity.

Carey, who was previously rep'd by Cindi Berger of PMK*BNC, is set to launch her residency at Caesars Palace Las Vegas on May 6, and signed a new recording contract with Epic Records earlier this year. Her new album #1 To Infinity is set for release May 18.
