Although the Season 2 finale of NBC's hit singing competition "The Voice" will focus on who'll be crowned the winner, viewers will also be treated to a star-studded lineup of special performances from Lady Antebellum, Justin Bieber, Flo Rida and Daryl Hall and John Oates.

Lady A will perform "Wanted You More" on the telecast, reports HuffPost TV, while Flo Rida will perform the hit "Wild Ones." Hall and Oates will treat viewers to their 1977 No. 1 smash, "Rich Girl" and Justin Bieber will be on hand for the world-premiere performance of his hit single, "Boyfriend."

The four contestants heading into next week's finals are Jermaine Paul (Team Blake Shelton), Chris Mann (Team Christina Aguilera), Juliet Simms (Team Cee Lo Green) and Tony Lucca (Team Adam Levine).
