“The Voice” karaoke night was held Thursday at Hyde Sunset, Los Angeles, Calif.

Coaches Adam Levine, Blake Shelton, Christina Aguilera and Pharrell Williams turned the tables on press in the name of raising money for Children’s Hospital Los Angeles. KOST-FM’s Ellen K hosted the event.

“The Voice” is a reality television singing competition broadcast on NBC. Based on the original “The Voice of Holland,” the concept of the series is to find new singing talent (solo or duets) drawn from public auditions
