The mentors on The Voice US may be superstars, but the consensus is it's not on them that the singing competition show has failed to find big stars such as themselves.
Adam Levine, Christina Aguilera, CeeLo Green and the show's host and producer Carson Daly addressed journalists at the Television Critics Association summer press tour. The remaining mentor, Blake Shelton, did not attend because he's on tour.
During the panel, Adam said finding a star "would be really nice" but it's not the goal.
"A lot of things have to happen in order for that to take place," he said. "I think the goal of the show is to do what we can do for these amazing singers while they're on the show ... I think that we all know that the lightning in a bottle you have to capture in order to be successful in this business is extraordinarily difficult. I'm not sure that that is the overall mission statement of the show."
Christina said it's unrealistic to expect someone to turn into an overnight sensation and cites her own career as an example.
"It's not like everything needs to be like boom, boom, boom, then record deal, then number one success. It doesn't happen like that. It didn't happen that way for me either.
"Like, for instance ... my experience with The Mickey Mouse Club, the alumni from that show, you know, you have huge names Britney (Spears), Justin (Timberlake), Ryan Gosling, you know, all these names come from that show. But, you know, right after the show, did we rocket to success right after it? No. It takes time."
Of season four winner, Danielle Bradbery, The Voice host and producer Carson Daly argued that she has time on her side.
"She has eight years to figure it out, her voice, an album, whatever it might be. And in eight years she'll be the same age as Taylor Swift is right now. She's got time," he said.
Danielle's new single The Heart of Dixie debuted at number 58 on the Billboard Hot 100 and number 16 on the country charts.
The Voice returns for its fifth season in the US on September 23.
