The roster of talent on "The Voice" keeps getting more crowded, as now Missy Elliott has signed on to serve as an adviser for Pharrell Williams' team on the singing competition, which returns Sept. 21, according to E! News. Previous advisers for Williams' team have included Lionel Richie and Alicia Keys, so it will be interesting to see what advice someone who is not necessarily a singer has for the contestants.

For the ninth season, Elliott joins the adviser ranks that already include Selena Gomez for Gwen Stefani's team and Brad Paisley for Blake Shelton's. Adam Levine, on the other hand, is going with … John Fogerty? Sure, I guess. And, as NBC previously announced, Rihanna will be advising all contestants, regardless of spinny-chair judge affiliation.
