The first season of "The Voice" featured Cee Lo Green and Christina Aguilera as coaches. The artists Usher and Shakira have also served as coaches at various points in the program's nine-season run. As of 2015, Stefani is serving as a replacement coach for Aguilera during her pregnancy and maternity leave.
