“I haven’t talked about it yet,” Stefani said on The Talk, “because it was such a shock. I wanted to come back so bad. I mean, the show is so fun.” Stefani was last on The Voice in spring 2017. Stefani said working with boyfriend Blake Shelton again will be "fun" and "exciting." “I mean, Blake’s my best friend, so I get to hang out with him at work,” Stefani said.
