LOS ANGELES, California (X17online) - NBC has announced more celebrities that will appear on its new singing competition show, The Voice.

Singers Reba McEntire, Monica and Sia (Australia's Sia Furler) along with music producer Adam Blackstone will join the series as advisers to the talent coaches, who include Christina Aguilera, Cee Lo Green, Adam Levine and Blake Shelton.

The Voice premiered this week to strong numbers. It next airs May 3.

Aguilera will team up with singer/songwriter Sia, Levine with Blackstone, Green with Monica and Shelton with veteran and fellow country singer Reba.

The advisers are part of what NBC promised its coaches would do: bring their personal friends and members of their music teams to help them on the show. Blackstone, for example, is music director for Levine's band Maroon 5.

Shelton and McEntire co-hosted this year's Academy of Country Music Awards in early April and just announced that they will also host a Tornado Relief Concert May 26 in Oklahoma to benefit victims of this year's many tornadoes throughout the Midwest and South.
