CeeLo Green, Gwen Stefani, and Usher are returning to 'The Voice'

The Voice is throwing its biggest reunion yet.

Former coaches CeeLo Green (seasons 1, 2, 3, and 5), Gwen Stefani (season 7), and Usher (seasons 4 and 6) will return to the show on Monday, April 27—but don’t expect a knockout battle for the big red chairs. They’ll be serving as advisors to the eight remaining singers in season 8, working with current coaches Adam Levine, Christina Aguilera, Pharrell Williams, and Blake Shelton.

This means that aside from Shakira (seasons 4 and 6), every past and present Voice coach will appear in next week’s episode. Levine, Aguilera, Shelton, and Green were the firs four to sit in those trademark red chairs.

Stefani shared the news on Twitter.

No word yet on which teams the other advisers will mentor.
