No Doubt singer Gwen Stefani is set to replace the pregnant Christina Aguilera as a coach during the 7th cycle of The Voice, which begins taping in June.

Gwen Stefani has also been in talks to become a coach on ABC's Rising Star, which premieres in August. She has experience working in these competition shows, having mentored for American Idol.

She will be joining other new cast member Pharrell Williams, who is stepping in to replace CeeLo Green. Gwen Stefani and Pharrell Williams recently joined each other on the Coachella Music & Arts Festival main stage, where they performed Gwen's 2005 hit 'Hollaback Girl'.

Pharrell Williams has already served time on The Voice, being advisor to Team Usher, where he performed the hit single 'Blurred Lines'.

The Voice hit a series low last week as it entered playoffs. It was still the highest rated show of the night. This week saw a small tick up in ratings. Will Gwen Stefani and Pharrell Williams help bring a fresh audience to the show?
