As the current season of "The Voice" winds down, Blake Shelton says he's sad that his girlfriend Gwen Stefani won't be back for the next round of the show. 

He tells Extra, "I don't want Gwen to not be on the show. Why can't we have a fifth coach?" 

Gwen won't be sitting idle, though. She plans to spend her time away from "The Voice" working on a new album. It's expected that Christina Aguilera will return to the show for season 10.
