You may or may not have heard teen pop sensation Justin Bieber announce he'll perform his new single, "Boyfriend," first on the season finale for The Voice.
But show mentor/coach Blake Shelton will have some country cousins along as well. Lady Antebellum will be among the three other superstar acts set to perform alongside the Biebs.
The other two are Hall & Oates, who'll perform "Rich Girl," and rapper Flo Rida, who's, uh, rapping "Wild Ones."
The show airs May 8, when this season's champ will be crowned. Repping Team Blake is Jermaine Paul, who's up against fellow contestants Chris Mann, Juliet Simms and former Mousketeer Tony Lucca.
