The live finale of NBC's 'The Voice' is shaping up to be a star-studded show. Justin Bieber, Flo Rida, Lady Antebellum and Hall & Oates will all take the stage as part of the season two finale on Tuesday, May 8.

Justin Bieber first stopped by 'The Voice' on April 17 to show a preview of his new music video for the song "Boyfriend," and Carson Daly asked if he'd return to perform the song live for the first time.

Check out the video:

Bieber obliged, of course, and he joins a list of big names who will also be performing on the show's season two finale.

Flo Rida will perform a medley of songs including his latest smash, "Wild Ones," and Lady Antebellum will perform their song "Wanted You More".

Hall & Oates will perform their first ever #1 single, "Rich Girl."

On Monday, May 7, Team Adam, Team Blake, Team Cee-Lo and Team Christina will battle it out one last time before a winner is crowned Tuesday, May 8 on NBC.
