The Voice is about to get a little crowded: Former coaches Gwen Stefani, CeeLo Green, and Usher will return for April 27 episode.

The show's big red coaches' chairs are currently filled by Adam Levine, Blake Shelton, Pharrell Williams, and Christina Aguilera. But Stefani, Green, Usher will stop by next week to offer extra expertise to the Season 8 finalists, according to People.

This will be quite a reunion: Green appeared on the singing competition from its inception through the third season and returned for Season 5 while Usher was a judge for both Seasons 4 and 6. Stefani, who was a judge for the last season, tweeted about the homecoming:

It's likely to be a memorable show but we have one question: Where is everyone going to sit?

The Voice airs Mondays and Tuesdays at 8 p.m. ET on NBC.
