Over the years, American Idol has attracted many top stars to its finales, so why should The Voice be any different?  The NBC show has just announced that the May 8 finale will include performances from Justin Bieber , Flo Rida and Lady Antebellum .

Justin, who appeared on The Voice a few weeks ago to premiere a snippet of his video for "Boyfriend," will return to perform that song on TV for the first time.  Flo Rida, meanwhile, will perform a medley of his hits, including his latest, "Wild One."  As for Lady Antebellum, they'll perform "Wanted You More," a track from their current album Own the Night .

During the two-hour finale, the winner of The Voice season two will be crowned.  You may recall that last year, the winner was Javier Colon , from Team Adam.  Actually, we're sure you recall, since Adam Levine never stops reminding his fellow judges of that fact.
