Gwen Stefan

The Voice may be welcoming another new face this fall.

Gwen Stefani has reportedly signed on as a coach for the show's seventh season, TMZ.com reports.

Stefani, 44, would replace Christina Aguilera, who announced her pregnancy in February. NBC declined to comment on the report.

Last month, NBC announced that Pharrell Williams would be stepping in as a coach after Cee Lo Green announced he was permanently exiting the singing competition series in February. Blake Shelton and Adam Levine are expected to return, but only Williams has been confirmed for Season 7, which begins shooting in June and will debut sometime this fall.

Stefani and Williams are no strangers to working together. Just last week, Stefani appeared onstage during his set at Coachella to sing her hit "Hollaback Girl," which they co-wrote nearly 10 years ago. Stefani was also featured on Williams' first solo single, "Can I Have It Like That," back in 2005.

The Voice, which is about to begin live rounds for Season 6, airs Mondays and Tuesdays at 8/7c on NBC.

Do you think Stefani would be a good fit for The Voice?
